Plexiglass is a popular name. The chemical name of this polymer transparent material is polymethyl methacrylate, which is polymerized by methyl methacrylate.
The difference from ordinary glass:

2.1 High transparency. Plexiglass is currently a relatively good polymer transparent material with a light permeability of 92 %, which is higher than that of glass. The lamp tube of the solar lamp called artificial small sun is made of quartz because quartz can completely penetrate ultraviolet light. Ordinary glass can only penetrate 0.6 % ultraviolet light. But organic glass can penetrate 73 %.

2.2 High mechanical strength. The relative molecular mass of the Plexiglass is about 2 million, it is a long-chain polymer compound, and the chain forming the molecule is very soft, so the strength of the Plexiglass is relatively high. The tensile and impact resistance is 7 to 18 times higher than that of ordinary glass. There is a kind of organic glass that has been heated and stretched. The molecular chain segments are arranged in a very orderly manner, resulting in a significant increase in the toughness of the material. Nail into this kind of organic glass, Even if the nail penetrates, no cracks occur on the plexiglass. The plexiglass will not break into pieces after being penetrated by the warhead. Therefore, the stretched plexiglass can be used as bulletproof glass and also as a cockpit cover on military aircraft.

2.3 Light weight. Plexiglas have a density of 1.18 kg / DM 3.

2.4 Easy to process. Plexiglass can not only be cut by a lathe and drilled by a drill bed, but can also be bonded into various shapes by means of acetone, chloroform, etc.. It can also be machined by plastic molding such as blowing, injection, extrusion, etc. into aircraft canopy. Small to dentures and braces and other various products.
