Is acrylic considered a type of plastic?
437552
YES\n\nAcrylic is a useful, clear plastic that resembles glass, but has properties that make it superior to glass in many ways.\n\nAnother great advantage of acrylic is that it is only half as heavy as glass. This makes working with acrylic much easier. It can also be sawed, whereas glass must be scored.\n\nAdding to this favorable array of properties, a transparency rate of 93% makes acrylic the clearest material known. Very thick glass will have a green tint, while acrylic remains clear.\n\nThere are some misconceptions about acrylic, namely that it yellows, turns brittle and cracks over time. Though this might be true of very cheap forms of plastic, it is not so with acrylic. For example, the fighter planes of WWII have acrylic bubble-tops. Airplane windows are also acrylic. If taken care of, acrylic remains new looking regardless of age or exposure to sun. Some people worry that acrylic scratches too easily, but unlike glass, scratches can be easily buffed out of acrylic.\n\nI hope your doubt got clarified....Is isn't it?\n\nOtherwise check the following URL

Forty years ago, anything made of plastic was considered "cheap." That’s certainly not true today when plastics are used in thousands of products ranging from computers, automobile parts and important medical equipment to toys, cookware, sports equipment, and even clothes. And the plastics industry continues to grow rapidly. Just where do plastics come from?\n\nWhat are plastics?\n\nIt may surprise students to learn that gutta-percha, shellac, and the horns of animals—all naturally occurring substances—were used as plastic material before the first synthetic plastics were produced. Gutta-percha is derived from the sap of certain trees, and shellac is made from the secretions of a tiny scale insect. Before horn can be used, however, it must be "plasticized," or softened, by being boiled in water or soaked in an alkaline solution.\n\nThe first synthetic plastic was made from the plant material cellulose. In 1869, John Wesley Hyatt, an American printer and inventor, found that cellulose nitrate could be used as an inexpensive substitute for ivory. The mixture could be plasticized with the addition of camphor. Celluloid, as this new material was called, became the only plastic of commercial importance for 30 years. It was used for eyeglass frames, combs, billiard balls, shirt collars, buttons, dentures, and photographic film.\n\nIn 1951, two young research chemists for Phillips Petroleum Company (now ConocoPhillips) in Bartlesville, Okla., made discoveries that revolutionized the plastics world. Today, the plastics they discovered—polypropylene and polyethylene—are used to produce the vast majority of the thousands of plastics products all over the world. (Read more about their discoveries in "Serendipity, Science & Discoveries" in this publication.)\n\nThe source for today’s wide variety of plastics? Petroleum.

Mostly they use Isoproyle butane... not harmful to plastic.

cellophane is a plastic but not all plastics are cellophane.   Nylon is a plastic. Teflon is a plastic. etc...\n\nMaking Cellophane\n\nIn the manufacturing process, an alkaline solution of cellulose fibres (usually wood or cotton) known as viscose is extruded through a narrow slit into an acid bath. The acid regenerates the cellulose, forming a film. Further treatment, such as washing and bleaching, yields cellophane.

There are all kinds of different materials lumped under the generic heading of "plastics".  The variations run into hundreds, perhaps even thousands of compounds!\n\nFor example, there's nylon.  The most familiar form, nylon 66, is a copolymer of adipic acid or adipoyl chloride and hexamethylene diamine.  But I can substitue various hydrocarbon chains in those two components to make nylon 55, nylon 65, nylon 48, nylon 83, etc.\n\nThen there are the families of polyaramid polymers, and polyester polymers, and polycarbonates, and . . . .\n\nNobody will ever be able to give you an exhaustive list here.  Try looking up some books on polymer chemistry at your library.

Acrylic distemper contain acrylates, a class of organic compounds which are used to make polymers such as perspex.\n\nSynthetic distempers include the acrylics.

Hey buddy  you may take  a  look at this  site which offers  this  kinda  services and explains everything slightly  good:http://www.e1.greatlakes.com/corp/prodserv/jsp/optical_monomers.jsp\n\nThis also:http://industrial-adhesives.globalspec.com/Industrial-Directory/monomer_MSDS_styrene\n\nand  about  acrylic glass:http://en.wikipedia.org/wiki/Polymethyl_methacrylate

it is plastic not Glass. a tip is to pull the plastic as tight as you can when fastening them down.

polymethacrylate resin is the synthetic polymer of methyl methacrylate. This thermoplastic and transparent plastic is sold by the tradenames Plexiglas, Perspex, Acrylite, Acrylplast, and Lucite and is commonly called acrylic glass or simply acrylic.

Rubber comes from a tree and plastic comes from oil. Therefore rubber is "natural" and plastic is not.

Plastic , because im trying to save the trees. Besides mother earth is highly upset how we been treating the earth these days.

Consider looking up Polycarbonate\n\nPolycarbonate is a clear polymer that is used in bullet proof glass.  It is commonly used nowadays in homes to resist breaks.  \n\nAcrylic is also used and is more flexible but less impact resistant.\n\nBoth of these materials are available at hardware stores such as Lowes.  If you seeking profession installation, just ask about the two materials, acrylic is cheaper then polycarbonate, usually by about 1/3 the cost.  \n\nIf you are only considering windows that resist breaking due to wind force, go for acrylic, its cheaper and the wind force, even at high pressure, may bend an acrylic panel, but will not break it.   \n\nThe polycarbonate will not only resist winds, it will flex less, and given the right thickness can stop a baseball bat or ball. crow bar, and even thicker, will repel small arms fire.  \n\nBoth materials flex to some degree, but return to their original flatness immediately.  Both materials are plastics and must have a UV protective coating to prevent "yellowing"  The protective coating, which is put on the outer surface, should be on any of the material you purchase that is intended for outdoor use.  The coatings guarantee no yellowing for 10 years.\n\nmore FYI, The combination of the two materials is used by a particular company to make one-way bullet proof "glass" really  sandwich of the two materials, with the more flexible acrylic on the bad guy's side.

You can find international suppliers at the reference.  It appears that many materials are used including plastic and aluminum.

Modern materials science tends to classify materials into the following categories:\n\n1. Metals (this includes pure metals and alloys)\n2. Ceramics\n3. Polymers\n\n4 (sort of). composites\n\ncomposites are generally not considered to be an actual material type because a composite is simply a combination of 2 or more different material types, for example a metal matrix ceramic material would be a composite.
