Polycarbonate is colorless and transparent, heat-resistant, impact resistant, flame retardant BI grade, and has good mechanical properties within normal usage temperatures. Compared to polymethyl methacrylate, polycarbonate has good impact resistance, high refractive index, good processability, and UL94 V-2 flame retardancy without the need for additives. However, compared to polycarbonate, polymethyl methacrylate has a lower price and can be used to produce large devices through bulk polymerization.
The three major application fields of PC engineering plastics are glass assembly industry, automotive industry, electronics and electrical industry, followed by industrial mechanical parts, optical discs, packaging, office equipment such as computers, medical and health care, film, leisure and protective equipment, etc. PC can be used as door and window glass, and PC laminates are widely used for protective windows in banks, embassies, detention centers, and public places. They are also used for aircraft cabin covers, lighting equipment, industrial safety barriers, and bulletproof glass.
