PMMA CONCEPT: PMMA is a polymer transparent material, the chemicalname is poly(methyl methacrylate) , which is made from methylmethacrylate. Commonly known as: Perspex (also known as acrylic) .PMMA CHARACTERISTICS: 1 High Transparency. The PERSPEX is the mostexcellent transparent polymer material at present, thetransmittance reaches 92% , which is higher than that of glass. Thetubes of the solar lamp, called the artificial little Sun, are madeof quartz because quartz is able to see through ultraviolet light.Ordinary glass can only pass through 0.6% UV light, but plexiglasscan pass through 73% . 2 High Mechanical Strength. PMMA has amolecular weight of about 2 million, is a long chain ofmacromolecule, and the chain forming the molecules is very soft, sothe strength of PMMA is relatively high, tensile and impactresistance than ordinary Glass 7-18 times higher. There is a typeof polymethyl methacrylate that has been heated and stretched, inwhich the molecular segments are arranged in a very orderly manner,resulting in a significant increase in the toughness of thematerial. A nail is driven into the PLEXIGLASS, and even if thenail penetrates, no cracks are produced on the plexiglass. Theplexiglass also does not break into pieces when shot through. As aresult, the stretched plexiglass can be used as a Bulletproof glassand as a canopy on military aircraft.
3. Light weight. The density of pmma is 1.18 G / CM3; for amaterial of the same size, its weight is only half that of ordinaryglass and 43% that of aluminium (a light metal) . 4 easy toprocess. The organic glass can not only be cut by a lathe anddrilled by a drilling machine, but can also be made into largeairplane canopy by means of blow molding, injection molding,extrusion and other plastic forming methods, everything fromdentures to braces.
