Polycarbonate is a non-crystalline thermoplastic material, featuring excellent heat resistance, good transparency, and very high impact strength, among its physical and mechanical properties. PCHigh strength and elasticity coefficient, high impact resistance, broad temperature range, high transparency, and freedom to dye.Excellent fatigue resistance, weather resistance, and electrical properties for PC.Polycarbonate is an excellent E(120℃) grade insulating material, used for manufacturing insulated connectors, coil frames, tube sockets, insulating sleeves, telephone casings and parts, battery cases for miner's lamps, and more. It is also suitable for producing high-precision components, such as CDs, telephones, computers, video recorders, telephone exchanges, signal relays, and other communication equipment. Polycarbonate film is widely used in capacitors, insulated sleeves, recording tapes, color video tapes, and more.
