Polycarbonate (PC) is a thermoplastic polymer with a wide range of applications. It is produced by chain growth polymerization of monomer propylene. It is a white strong material with high chemical resistance. PP can also maintain electrical stability under humidity and high temperature, therefore it become an ideal material for manufacturing electronic and electrical parts. The three major application areas of PC engineering plastics are the glass assembly industry, the automobile industry and the electronics and electrical industry.
