2. High mechanical strength. The relative molecular mass of organic glass is about 2 million, which is a polymer compound of a long chain, and the molecular chain is very soft. Therefore, the strength of the organic glass is relatively high. 18 times. There is an organic glass that has been heated and stretched, and the molecular chain segments are arranged in order, which significantly improves the toughness of the material. Nail with nails into this organic glass, even if the nail penetrates, no cracks are produced on the organic glass. This organic glass will not be broken into pieces after the bullets are penetrated. Therefore, the stretching organic glass can be used as a bulletproof glass, and it is also used as a cockpit cover on a military aircraft.
3. Light weight. The density of the organic glass is 1.18kg/dm3. The material of the same size is only half of the ordinary glass and 43 % of the metal aluminum (belonging to light metal).
4. Easy to process. Organic glass can not only cut the lathe, drilling the machine drilling, but also can be used to use acetone and chloroform into various shapes. It can also be processed into a large -scale method of plastic molding, injection, and extrusion. The cockpit cover is as small as denture and dental support.
