聚碳酸酯PC 2405 透明级 高流动 高强度 电子电器原料 (CAS No.None)

Product Name:Polycarbonate PC 2405

English Name:Polycarbonate PC 2405

CAS No.:25037-45-9

Aliases:PC 2405, Polycarbonate resin

Molecular Formula:(C16H14O3)n

Physical Properties:Polycarbonate is a transparent, slightly yellow or white amorphous thermoplastic resin with excellent mechanical properties, heat resistance, cold resistance, fatigue resistance and electrical insulation. It has high light transmittance, good dimensional stability, and is generally resistant to solvents but susceptible to hydrolysis at high temperature and humidity. Density is about 1.20 g/cm³, refractive index 1.585, glass transition temperature about 150°C, heat deflection temperature 130–140°C, and long-term service temperature range -60 to 120°C.

Uses:Used for manufacturing large lamp covers, protective glass and optical instrument parts; in electronic and electrical fields for insulating connectors, coil frames, tube sockets, housings, optical discs, computer components and signal relays; in machinery for gears, bearings, worms; and in medical devices for drug containers and surgical instruments. As a transparent, high-flow and high-strength grade, it is especially suitable for precision thin-wall electronic and electrical parts.
