Polycarbonate is an amorphous thermoplastic, high impact transparent plastic that can be used continuously at a temperature of 135-145 DEGC. Polycarbonate has excellent electrical insulation, elongation, dimensional stability and chemical resistance; also has self-extinguishing, easy to enhance, flame-retardant, non-toxic, hygienic, capable of coloring and other properties. 　　

Polycarbonate (PC) is a high molecular polymer containing a carbonate group in its molecular chain. Due to its structural speciality, it makes it the only transparent plastic among the five engineering plastics (polycarbonate, polyoxymethylene, polyamide, thermoplastic polyester, and modified polyphenylene ether).At the same time, it has a combination of high strength, ductility, and toughness. It is widely used in electronic appliances, home appliances, building materials, automobile manufacturing, medical equipment, optical media materials, packaging materials and other fields. At present, the material has become the fast growing general engineering plastic in the five major engineering plastics.
