pc (polycarbonate), the English name Polycarbonate, referred to as PC, is the main chain of molecules containing -[O-R-O-CO]-linked thermoplastic resins, according to the molecular structure of the ester group can be divided into aliphatic, alicyclic, aliphatic and aromatic, which has a practical value is the aromatic polycarbonate, and the most important bisphenol A-type polycarbonate molecular weight is usually 3-10 million. The practical value of the aromatic polycarbonate, and to bisphenol A polycarbonate is the most important, molecular weight is usually 3-10 million. It is a thermoplastic engineering plastic with high mechanical, optical, electrical and thermal properties. This extremely tough, easy-to-process polymer is adapted to a variety of applications: household appliances, automotive lamps, medical instruments, and packaging containers, for example.
The development of high-purity, optical-grade polycarbonate (OQ resin), in turn, has contributed to the growth of the optical disk industry.
