Polycarbonate (PC) is a molecular chain containing carbonate base polymer, according to the structure of the ester base can be divided into aliphatic, aromatic, aliphatic, aromatic, and other types.Because of aliphatic and mechanical properties of aliphatic and aromatic polycarbonate is low, which limits its application in the field of engineering plastics.There are only aromatic polycarbonate won the industrialized production.Due to the particularity of polycarbonate structure, has become the fastest growing in the five engineering plastics of general engineering plastics.
1.Properties
PC is characterized by high transparency, high impact resistance, high hardness, high creep-resistance, excellent dimensional stability, good resistance to low-temperature and heat, flame retardance, ease to process, and excellent sound insulation

Application
1>. PC is made into large bulb shade, protective glass, the right and left eyepiece tube of optical instruments. Also, it is used as the transparent materials in plane.
2> . PC is good insulation, made into insulated connector, coil frame, tube socket, insulating sleeve, telephone housing and parts, miner's lamp battery shell. Also, it is used to make fine parts of communication equipment, such as CD-ROM, telephone, computer, video recorder, telephone switches, signal relay. The PC film is used for capacitors, insulation foreskin, recorder, color video tape. etc
4>. PC can be made into cap, tube, bottle and dental equipment, drug containers and surgical instruments. Even be used as an artificial kidney, artificial lung and other artificial organs.
5>. For architectural, PC can be made into Double-wall hollow bars, glass of greenhouse. For textile industry, PC is suitable for making bobbin, textile machine bearing. For daily, PC is good material can be made into tableware, toys and models.
Packing: 25kg/bag, 22 ton to one 20ft container.
