The Difference Between The Transparent Vetrosa And Ordinary Glass
Plexiglass is a popular name, this polymer transparent material chemical name called polymethyl methacrylate, is made of methyl methacrylate polymerization.
Differences with ordinary glass:
① highly transparent. Plexiglass is the most excellent polymer transparent material, light transmission rate of 92%, higher than the glass transmittance. The lamp that is called the sun of the artificial sun is made of quartz, because the quartz can pass completely through the ultraviolet rays. Ordinary glass can only pass 0.6% of the UV, but plexiglass can pass through 73%.Transparent Vetrosa
② high mechanical strength. Plexiglass has a relative molecular mass of about 2 million, is a long chain of polymer compounds, and the formation of molecular chain is very soft, so the plexiglass strength is relatively high, tensile and impact resistance than ordinary glass 7 ~ 18 times. There is a heated and stretched plexiglass in which the molecular segments are arranged in a very orderly manner, resulting in a significant improvement in the toughness of the material. Nail into this plexiglass, even if the nail penetrated, plexiglass does not produce cracks. This plexiglass is not broken after the bullet breakdown. Therefore, the piled plexiglass can be used as a bulletproof glass, also used as a cockpit on a military aircraft.Transparent Vetrosa
③ light weight Plexiglass density of 1.18kg / dm3, the same size of the material, its weight is only half of ordinary glass, metal aluminum (belonging to light metal) 43%.Transparent Vetrosa
④ easy to process. Plexiglass can not only use the lathe for cutting, drilling machine drilling, and can use acetone, chloroform and other objects into a variety of shapes, but also with blow molding, injection, extrusion and other plastic molding method into large aircraft Cockpit cover, small to dentures and dental care and other products.Transparent Vetrosa
