Polycarbonate (PC) resin is a kind of high performance thermoplastic engineering plastics, has outstanding impact resistance, creep resistance and good dimensional stability, heat resistance, low water absorption, non-toxic, excellent dielectric properties, is the five largest engineering plastics only has good transparency products, general engineering plastics in recent years the fastest growth. At present, it is widely used in automotive, electronic and electrical, construction, office equipment, packaging, sports equipment, health care and other fields. With the deepening of modification research, it is rapidly expanding into aerospace, computer, compact disc and other high-tech fields.
