Polycarbonate (PC)
Polycarbonate (abbreviated as PC) refers to a non-crystalline thermoplastic high molecular polymer containing a carbonate group (-COO-) in a molecular chain. It is a thermoplastic engineering plastic with excellent comprehensive performance. Its excellent performance in mechanical, optical and thermal properties makes it have three characteristics of high impact resistance, high transparency and high heat resistance. It is a durable engineering plastic.
Characteristics
The product has four comprehensive characteristics of transparency, toughness, heat resistance and flame retardancy.
Wide temperature range, stable performance over the temperature range of -100 ° C ~ 129 ° C
High heat reflection temperature
Low molding shrinkage and good dimensional stability
Excellent electrical characteristics
Application
As a thermoplastic engineering plastic with excellent comprehensive performance, ZPC polycarbonate products can be mainly used in optical lighting, electrical and electronic, automotive, construction, packaging, etc., and can be made into plastic alloys with other resins to meet specific needs.
