Short Background OF PLASTICS - Specially PLEXIGLAS ACRYLIC SHEET


Right before occurring to the next subject matter, we want to briefly illuminate over the record of plastics and their introduction into the industrial and customer Modern society. As we talked about, the definition on the term plastic should be to variety or model anything. In this light-weight it is possible to recognize that wood, clay, glass and vegetable fibers ended up the plastics of early person who shaped and baked these components to his have requires. With the coming of the commercial Revolution came man's exploitation of all-natural means and experts in western civilization started to experiment Using these means and natural and organic substances.

The first vital day within our historical past guides demonstrates us that a compound known as urea was found and isolated inside the urine of mammals as well as other larger varieties of animal daily life. This celebration befell from the 12 months 1773, nonetheless it wasn't right until 1828 that urea was synthetically created and the inspiration for phenol-formaldehyde plastics was laid. In 1843 an acrylic acid planning was noted and in 1901 Dr. Otto Rohm revealed the final results of his researches with acrylic resinoids. By 1909 the primary patent for phenol- formaldehyde plastics was secured by Dr. Leo Baekeland. he identified that phenol and formaldehyde when blended fashioned a resinous substance, a phenolic plastic which he called "Bakelite". It was a plastic -- it may be softened with heat and after that molded into condition and established into last sort by continued heating stressed whilst in the mold. Baekeland's discovery brought on the Innovative creativity of natural and organic chemists and study commenced the entire world around extra intensely than ever before in advance of.

Sure, in 1914, the founding business that grew to become Ridout Plastics started advertising those compact quantities and letters produced from cellulose plastic.

Acrylic resins were being to start with geared up In this particular place in 1931 for industrial coatings and laminated glass binders. The higher acknowledged spinoff of methacrylic acid, polymethyl methacrylate, wasn't released right until 1936 for a clear sheet As well as in 1937 as being a molding powder. Therefore the start in the acrylic era and Plexiglas. Acrylic sheet played a crucial part in World War II as bullet resistant glazing in our warplanes. It had been observed to be light-weight and really solid and could be simply shaped to fit in to the structural styles in the aircraft. To today, the Plexiglas windows in These planes remain apparent and totally free from yellowing; weatherability of Plexiglas is among its most well known characteristics, a little something no other plastic glazing can match. Plexiglas quickly discovered its way into homes and factories for protection glazing, electrical and chemical apps, skylights and windscreens and numerous other valuable apps.

INTRODUCTION TO PLEXIGLAS, LUCITE, PERSPEX ACRYLIC SHEET


Plastics have arrive of age throughout the last seventy five several years. The material has advanced from a synthetic "substitute" for other materials to some beneficial new Uncooked content. It now occupies a everlasting area in out engineering and would be the basic product of the longer term.

This primer is meant to familiarize you with the chances of plastics; most specifically acrylics.

Two hundred yrs in the past, if the pioneers and early settlers ended up setting up shelters and towns, they used to use the fabric means in the land; as structural resources, as household furniture, and as ornamentation to the things they built. They selected their products very carefully with an eye on the intent the completed product would provide. Wood, for instance, arrived in different strengths and hardness. Some stone may be quarried and Minimize more conveniently than Other individuals. Many metals ended up fashioned for various uses. These early builders and craftsmen discovered which type of accessible Uncooked materials could be most fitted for unique responsibilities. Technological innovation has come of age, and now we have access to resources supplying a number of use further than those fundamental wants of shelter, furnishings and decoration. One of An important of those resources is plastic, and plastic is exactly what this primer is about.

If we Have a look at the definition of the word plastic, it might help us to know what is so thrilling and distinctive about this material. One finds the phrase Utilized in a creative feeling as sculptural and characterized by modeling or molding with the surfaces. Therefore, an item of art may be described as currently being plastic or as owning a substantial amount of plasticity. Webster ties the word plastic towards the Artistic forces in mother nature and the adaptability of animals in their setting. Aiming to the Greek root on the term plastic, plastikos, we discover the definition as staying to mold or sort something. You can agree then the term plastic is a great term for describing this important material which has uncovered long lasting household in our life.

There's two fundamental kinds of plastics: Thermoset, which, when formed, stay while in the formed shape and cannot revert to a liquid condition, the ultimate shape is ready in the production stage, and thermoplastics which, when heated to forming temperatures, are pliable and can be reshaped.

Examples of thermoset plastics can be found in your house, in your automobile, even in many of the sporting merchandise you use. One of many earliest plastics found out and place into professional service have been phenolic resins. This was a cloth which could get not simply significant impression, but was both equally warmth and chemically resistant. Modern-day usage of phenolics is usually observed from the Personal computer boards of your respective good state Television, the cope with of one's buck knife, along with your espresso pot, as well as the pulleys and cleats of one's racing yacht.

Using thermoplastics is by far the chief in the present industrial Culture. The packaging field calls for far more plastics at an ever escalating charge. Choose Yet another look at that comfortable consume bottle up coming time you pour from it. Thermoplastics are playing an essential section in saving Electricity for The usa.

Plexiglas storm Home windows are already in provider for various many years and new glazing supplies like Twinwall sheets are offering its people insulation advantages of as much as 40% improved thermal retention than plate glass by yourself. Plastics will increase the beauty of our long run vehicles although shaving off hundreds of lbs of excess excess weight per car. From the model 12 months 1979, Detroit has employed nearly a million a ton of mixed types of plastics inside their endeavours to achieve these Vitality targets.

So we find that acrylics fall into your thermoplastics category, meaning they can be shaped when heated to the appropriate temperature. Their chemical composition is always that of a transparent, water-white, transparent liquid compound of monomer that could be polymerized into sheets, rods, tubes, molding pellets and additives. Additives are principally Employed in the creation of other resources, e.g., multi-grade oils, other plastics, paints, and ground polishes. So imagine acrylics as a whole new "Uncooked" materials. A cloth as essentially critical as the normal resources of wood, metallic stone, and so on.

Acrylic is usually a by-product of pure gas: see chart beneath.

Actual physical Qualities OF PLEXIGLAS, LUCITE, PERSPEX ACRYLICS


Acrylic plastic sheet is developed in quite a few formulations to provide unique physical Qualities necessary for many kinds of applications. Generally speaking, even so, the Bodily properties of acrylics are:

Transparency - In colorless form acrylic plastic is as transparent as the best optical glass. Its full white light-weight transmittance is ninety two%, the highest transmittance physically achievable of any material.

Breakage Resistance - Acrylic sheet has from six to seventeen periods larger impact resistance than normal glass in thicknesses of .125" to .250". When subjected to blows past its resistance, acrylic sheet cuts down the hazard of personal injury because it breaks into significant fairly dull edged pieces which disperse at minimal velocity, due to the gentle fat of the fabric.

Weather Resistance - The many years of precise outdoor publicity of acrylics in a wide variety of programs, proving its temperature resistance, can't be matched by any other clear plastic materials.

Chemical Resistance - Acrylic plastic has outstanding resistance to most chemicals, which includes alternatives of inorganic alkalis and acids for instance ammonia and sulfuric acid, and aliphatic hydrocarbons such as hexane, octane and VM&P naphtha. It truly is attacked by the subsequent chemical substances:

Gasoline

Chlorinated hydrocarbons including methylene chloride, a solvent cement greatly employed, and carbon tetrachloride.

Aromatic solvents for instance turpentine, benzene, and toluene.

Ethyl and methyl Alcoholic beverages.

Natural acids like acetic acid, phenols, and lysol.

Lacquer thinners and various esters, ketones, and ethers.

Light Body weight - Acrylic sheet is lower than 50 percent as significant as glass: it really is forty three% as heavy as aluminum and 70% as large as magnesium.

Dimensional Steadiness - Acrylic sheet is noteworthy for its independence from shrinking and deterioration as a result of prolonged periods of use. Quite a few drawing devices necessitating correct dimensional security happen to be fabricated from Plexiglas.

Combustibility - Acrylic sheet is a combustible thermoplastic and may be addressed as a normal combustible content for example Wooden. The self ignition temperature (spontaneous combustion) of acrylic is amongst 850 degree F and 869 diploma File. The temperature at which the material will ignite inside the existence of the flame is involving 550 degree File and 570 diploma F. While the ignition temperatures of acrylic are greater than that of most woods, it burns vigorously and generates heat speedily when linked to hearth. The primary solutions of acrylic combustion are carbon monoxide and carbon dioxide, having said that, burning acrylic plastic will not make either abnormal portions of smoke or gasses extra poisonous than those made by burning wood or paper. Notice hearth safety measures appropriate for equivalent forms of wood and paper products.

Warmth Resistance - The most "continuous service temperature" of acrylic is involving 180 levels F and 200 levels F dependant upon the certain use. Consequently though the material can face up to bigger temperatures for extremely limited amounts of time, it's going to soften and drop its type or shape if subjected to these increased temperatures for any stretch of time. Though acrylics respond to warmth, they don't seem to be influenced by chilly, and will not likely come to be cracked or brittle in cold weather.

Electrical Houses - Acrylic plastics are afflicted merely a slight degree by weathering or moisture. Its floor resistivity is better than that of most other supplies, and helps make an excellent insulator.

U-Element - heat transfer by way of .187" thick acrylic is roughly 20% below by way of equivalent thickness of glass.

(0.187" acrylic = 1.09 BTU's/hr./sq. ft./ degree File with fifteen MPH and 0 degree File air on just one facet and 0 MPH and 70 degree File air on the other. 0.187" Glass = 1.23 BTU's/hr./sq. ft./diploma File underneath the same disorders).

Simplicity of Fabrication - It might be sawed, drilled, and machined like wood or gentle metals. When heated to your pliable state, Plexiglas might be fashioned to Just about any form.


FORMULATIONS OF PLEXIGLAS ACRYLICS


Ridout Plastics is happy to generally be a distributor for Plexiglas, the registered trademark or brand identify for acrylic plastic sheet, molding powder, and mirror created by Arkema Group of North The usa Corporation. (Acrylic is the generic name for this type of thermoplastic. Just as different auto manufacturers make several various designs of each and every vehicle, Arkema Team of North The usa manufactures various formulations of Plexiglas sheet and Plexiglas molding powder.) The different formulations for sheet are outlined down below:

Don't forget, when acrylic sheet is heated to forming temperature (325 F), it'll shrink 2.2 percent!

Extruded and Soften Calendered - the commodity sheet that's bought for most plastics providers is extruded product. This method consists of heating the molding compounds until finally a clear viscous materials can be forced amongst huge, polished rollers that can specifically Manage the thickness of the fabric that is extruded. Thickness from .060" to .942" are made in this process in sheets as much as 108" huge. By transforming the rollers, unique floor textures can be utilized, including non-glare, or patio desk major textures. This grade is appropriate for most programs - other than skylights, aircraft, and fish tanks resulting from a reduce molecular composition. Use solvent cements for instance Weld On #3, #four and #sixteen. For Exclusive application a polymerizable two element cement, Weld On #forty may be used.

Ongoing Casting - Lucite Worldwide has a unique system inside the manufacture of Lucite XL acrylic sheet. They employ a pair of hugely polished metal belts that allow the sheet to variety on a constant basis, therefore the name, and permit for a greater molecular pounds. This content is restricted to use for spa, bath and kitchen area programs

Mobile Casting - This is the vintage and classic method of building acrylic sheet. Plexiglas G is the general function grade substance employed for some apps apart from Those people requiring a Specific mixture of Bodily Houses. Use solvent cements like Weld On #three, #four and #sixteen with Plexiglas G for a high quality bond. For Unique software a polymerizable two part cement, Weld On #forty may be used.

Mobile Casting - Preshrunk/UVA - Plexiglas II UVA (extremely-violet absorbing) sheets hold the exact same superb weathering qualities and precisely the same Actual physical Qualities as Plexiglas G, but are manufactured to military services technical specs which is utilized principally for aircraft glazing, plotting boards together with other scientific devices.

Reflective Acrylic - Plexiglas mirror is clear acrylic plastic sheet for indoor use, vacuum metallized with aluminum on its back again surface area. A troublesome opaque back-coat protects the metallized area. The graphic reflecting sheet, out there in many dimensions around forty eight" x 96" , is unique in comparison with glass mirror as well as other reflecting materials in flexibility of style, installation and assembly. It is actually light-weight body weight, breakage resistant and can be mounted additional simply and safely than glass mirrors. Plexiglas mirror could be Minimize with traditional saws and routers, and can be drilled and machined. It will also be fashioned by strip heating and bending, and may be surface decorated by silk-screening, spray painting or other artist's methods. Plexiglas mirror involves somewhat distinct fabrication techniques. To bond Plexiglas mirror to a different area, an acrylic Get in touch with cement, white silicone cement, or double faced foam tape should be applied. Solvent cements will dissolve the backing of your mirror.

Extruded & Mobile Cast - UltraViolet Filtering Plexiglas UF was made to block the destructive UV transmissions in daylight, mirrored sunlight, and from fluourescent lights. The degrading wavelengths are during the 280 - four hundred nanometer place. This material blocks ninety eight% with the transmissions. Offered in obvious and non-glare. Check our library site (over) to see the particulars.

Style Issues FOR PLEXIGLAS ACRYLIC SHEET


The main reason acrylic plastic is greatly Utilized in a great number of purposes is as it has a far better combination of Homes for selected sorts of jobs than other products including metals, woods, and glass. In addition, it has Homes which needs to be viewed as in design and style and installation. All elements have constraints - metals rust, woods warp, and glass breaks - nevertheless each is often a fundamental substance in marketplace simply because these limitations are taken into account in item design, installation and use. Likewise, the properties of acrylic sheet needs to be understood for the most effective use of the fabric. Bearing in mind these components in design, fabrication and installation will insure achievement during the concluded merchandise or part.

Pressure Restrictions - Acrylic sheet delivers excellent tensile, impact, and flexural power Homes as demonstrated inside the desk beneath; having said that, worry noticeably under the examination values shown will develop gentle floor checking or fractures referred to as crazing. To prevent crazing, masses must not exceed one,500 psi.

Tensile Toughness 10,five hundred psi (Tensile toughness is often a measure in the drive necessary to pull a specimen aside.)

Flexural Strength sixteen,000 psi (Flexural power is a evaluate in the pressure required to split a specimen by bending it.)

Compressive Strength 18,000 psi (Compressive toughness is often a measure of your compressive load needed to lead to failure.)

Modulus of Elasticity 450,000 psi (Modulus of elasticity is a measure in the force necessary to create a provided improve in dimension. A substantial modulus is associated with rigidity and a fabric's power to keep its shape less than momentary loading.)

Thermal Expansion and Contraction - All elements grow and deal to some bigger or lesser degree resulting from variations in temperature and humidity. Allowances needs to be made for these modifications in the development and fabrication of merchandise; as an example, the growth joints in cement sidewalks and on steel bridges. Acrylic sheet is subject to higher dimensional adjust, due to thermal expansion and contraction, than other elements with which it can be Employed in construction.

Comparison of Co-Efficient of Thermal Expansion

ACRYLIC SHEET VS. OTHER Components


Inches/Inch/File

Acrylic Sheet .0000410

Aluminum .0000129

Plate Glass .0000050

For indoor applications in which temperature Commonly continue being a similar (+/- 20 degrees File), acrylic sheet doesn't usually involve special factors for expansion and contraction apart from supplying for a snug in lieu of limited match because its movement is around 1/32 of the inch for every foot duration for each 20 levels of temperature change. In outdoor use exactly where temperature may differ widely, acrylic sheet ought to be dealt with in accordance with the following suggestions:

1. Sheets or panels should be mounted in a channel body partaking the edges of the material so that it's free to develop and deal without the need of restraint.

2. The channel body depth really should be sufficient to permit for thermal contraction in the sheet devoid of withdrawal of the perimeters in the frame.

three. As a result of-bolting or other rigid fastenings which never give for growth and contraction might result in failure from the installation.

4. Prior to set up inside the channel body, the sheet or panel really should be Minimize sufficiently shorter as opposed to channel frame Proportions to allow for thermal expansion.

5. Sealant compounds and tapes should be styles that are sufficiently extensible to accommodate thermal enlargement and contraction of the fabric and which adhere to the two sheet and frame. A sensible rule to abide by in out of doors installations would be that the frame depth should be one/4" as well as 1/8" for each functioning foot of acrylic sheet in duration and width to provide for contraction. To supply expansion clearance, the flat sheet need to be Reduce 1/sixteen" per managing foot shorter compared to body depth in the two Proportions.

Rigidity -Acrylic sheet is just not as rigid as all kinds of other products including metallic, Wooden, and glass. This can cause the fabric to deflect below load and foreshorten due to the deflection. Observation of the subsequent suggestions will add to The nice overall performance with the concluded portion.

one. Channels engaging the perimeters from the sheet should be adequately deep to allow for foreshortening in the sheet because of deflection underneath load, as well as thermal growth and contraction.

two. Thermoforming the sheet into dome-shaped or corrugated sheets improves its rigidity. Wherever realistic, formed panels must be used in large unsupported space usage, the place wind hundreds or snow hundreds are included.

three. If It's not at all simple to form the sheet, escalating the thickness of the flat sheet will impart larger rigidity towards the panel.

4. Yet another risk should be to insert a curved wedge below a Plexiglas skylight to offer it a convex condition.

five. As being a standard rule, any horizontal outdoor glazing for skylights, and so on., must be one/four" thickness for minimum deflection with highest unsupported span of 36".

Notch Sensitivity - Like glass and many other materials, acrylic plastic is notch sensitive. Notches and chipping along the perimeters on the sheet, at drilled holes, and inside of corner cuts are potential details of cracking or breaking. Scraping, sanding or joining the rough Reduce edges will remove these notches and insure the maximum affect resistance with the section. Inside corner cuts really should be avoided Any time feasible or at the very least be created to Have a very slight radius.

Floor Hardness - The area hardness of acrylic sheet is close to equivalent to that of copper or brass. Abrasives will scratch the surface of acrylic. This is simply not ordinarily a handicap in the usage of colored or patterned sheet but could possibly be a person in using clear sheet exactly where scratch-free of charge visual appeal is sought after. The workout of realistic treatment in cleansing colorless acrylic sheet will lower scratching.

Combustibility - Acrylic plastic needs to be used with an appreciation for The point that it is a combustible material. The hearth safeguards observed to protect wood along with other ordinary combustibles must be employed to safeguard acrylic plastic from ignition resources and involvement in fire. Purposes subjected to higher warmth resources of flame including superior wattage incandescent gentle bulbs, radiators, heaters, fire destinations or candles, etc. really should be averted. Products Commonly produced from non-combustible materials must be regarded as thoroughly before making them in acrylic being an unknowing person may possibly assume These are Secure when they could, in reality, existing a hazard.

Provider Temperature - The most temperature at which acrylic plastic might be subjected to for any stretch of time is 180 degrees File to 200 degrees File. The material softens when heated to temperatures previously mentioned 260 levels F that's forty degrees under the temperature used in thermoforming, and three hundred levels below its ignition temperature. Programs subjected to higher heat resources should be averted or temperatures checked to permit for an adequate safety factor. An alternate obvious plastic to employ will be Tuffak Polycarbonate with a provider temperature of 270 levels F.

Right STORAGE OF PLEXIGLAS SHEET


Plexiglas G sheets are covered or "masked" on both sides with a tough Kraft paper or polyethylene film coated by using a tension sensitive adhesive that does not attack the surface area with the Plexiglas. (Take note: Plexiglas might be requested unmasked plus some designs never come with masking.) The masking can help avoid scratching during usual managing and fabrication functions, and should be held in place for most slicing and machining processes. If your sheet is thermoformed, even so, or if it is installed outdoor the masking should be removed. The masking will guard the Plexiglas in the course of standard handling, but sheets should not be slid from each other or across rough or soiled surfaces.

Storage Rooms - Generally, the fire precautions which are noticed in connection with the storing of ordinary combustibles such as wood and paper needs to be observed when storing Plexiglas. In addition, storage rooms ought to be well ventilated. Air ought to circulate freely and may be reasonably moist and cool. The temperature ought to no exceed 125 degrees File. Storing Plexiglas sheet within a scorching, dry environment might finally lead to the adhesive utilized on the masking to dry out, rendering it tough to get rid of within the Plexiglas. Abnormal moisture may perhaps trigger the masking paper to deteriorate and reduce its success for safeguarding the Plexiglas.

Storage Racks - Masked sheets of Plexiglas are best stored on edge in "A" body storage racks. These racks give total support on the sheets yet allow simple removing of particular person sheets from any rack. If masked sheets need to be saved flat, care need to be taken in order to avoid trapping chips and Filth in between the sheets. These kinds of chips and dirt may possibly scratch or push to the surface of the fabric. Piles of Plexiglas sheet really should not be more than eighteen" superior. Tiny sheets really should be stacked around the much larger types to forestall unsupported overhang.

USE OF PLEXIGLAS ACRYLIC SHEET FOR Lights Apps


Lights Diffusers Making use of Fluorescent Lamps - Lights is usually constructed into ceilings and overhangs by putting in panels of white translucent Plexiglas down below fluorescent lamps, as demonstrated underneath. The Plexiglas panels rest within the projecting edges on the Wooden moldings or metal framing. If diffuser is outside, Reduce content 1/four" lesser compared to opening to allow for thermal growth of the fabric. For assistance usage of the lighting, the diffusing panels are pushed up, tilted and eradicated. Plexiglas in 1/4" thickness is usually recommended for installations with areas bigger than two square feet. For uniform diffusion of sunshine, the space from the Plexiglas towards the fluorescent lamps shouldn't be a lot less than two-thirds of the gap involving rows of lamps. All surfaces higher than the diffusing panels need to be specified not less than two coats of high-reflectance white paint, with white enamel to be a complete coat.

Lights Diffusers Working with Incandescent Gentle Bulbs - When working with Plexiglas within an incandescent lamp, you should supply adequate space for ventilation among The sunshine bulb and Plexiglas to prevent overheating and softening of the Plexiglas. For best success - even illumination and no warm places - use exhibit-scenario bulbs. The method for determining the minimum length amongst a provided wattage bulb and Plexiglas:

Minimal Distance, Bulb to Plexiglas = one/2 the sq. root of the bulb's wattage.

Take note: The least distance may be lessened by giving ventilation for warmth to escape, nonetheless there isn't any basic formula to ascertain the reduction.

A normal guideline for indoor applications of Plexiglas lights white is to implement:

Thickness Unsupported Horizontal Span

1/eight" 0" - 24"

three/16" 24" - 36"

one/4" 36" - forty eight"

ASSEMBLY AND FASTENING OF PLEXIGLAS ACRYLIC SHEET

By way of Fastening - Plexiglas may be simply hooked up to other surfaces employing round head Wooden screws, round head bolts, sheet metallic screws, oval head screws or bolts used along with ending washers, and threaded rod utilized with cap (Acorn) nuts. Flat head screws, bolts and various fasteners which demand countersinking really should not be utilised, simply because a countersunk gap is sort of the same as a notch and a possible fracture stage. The countersunk fastener also won't deliver freedom of motion for enlargement and contraction. Holes for fasteners ought to be drilled outsized to allow for thermal motion from the Plexiglas. Remember, acrylic and steel have distinctive enlargement prices. Generally, utilize a Plexiglas Drill Bit or regrind your steel little bit to the 60 diploma included suggestion angle. A minimal oversize for every drilled hole is usually recommended in the table underneath in accordance While using the dimension of your Plexiglas component along with the temperature vary to which the section is uncovered:

OVERSIZE HOLE Suggestions FOR By way of-BOLTING PLEXIGLAS

Anytime feasible locate holes to deliver at the least 1/four" of fabric from edge of hole to edge of Plexiglas sheet. If possible sleek inside hole by wrapping 320 grit wet or dry sand paper around a Wooden dowel and sanding until eventually smooth. Bring fastener up cosy and afterwards back off one/four convert, once again to supply for purely natural motion of the material because it expands and contracts. Yet again, the categories of recommended fasteners: spherical head screws or bolts, oval head screws or bolts utilised together with ending washers, and threaded rod employed with cap (Acorn) nuts

SKYLIGHTS & PATIO WINDBREAK FENCING

1. Constantly use 1/4" thickness of Plexiglas for all skylight programs. Thinner grades will deflect resulting from gravity and could cause drinking water puddles to gather. When masking lath style buildings with shading type framework, thinner grades of Plexiglas might be employed, but will not be encouraged. By-fastening is not really encouraged but with good drilling techniques with oversize holes and Plexiglas bits, it can be used satisfactorily.

two. With patio wind crack fencing spans of much more than two' x four' ought to one/4" Plexiglas on account of wind load deflection. Spans of a lot more than 4' should have a leading cap of wood to enclose the higher percentage of the Plexiglas panel. This can be still left off, but the very best from the Plexiglas panel may have a slight curvature. Make sure you let for this movement within the framing. Patio glazing needs to be framed in other wood or metallic channel frames.

Treatment AND CLEANING OF PLEXIGLAS ACRYLIC SHEET


You are now the very pleased proprietor of a fine bit of ACRYLIC. All of us at Ridout Plastics wish to supply these bits of wisdom to help you get the most price out of the buy.

The Number one Dilemma with acrylic is the usage of incorrect cleaners. Yes, we claimed "cleaners". Remember to... by no means, at any time, use cleaners that contains ammonia.
