PC engineering plastic is a polycarbonate resin formed from bisphenol-a in dihydroxyl compound and diphenylcarbonate in carbonate compound by transesterification (melting process). It is an excellent thermoplastic engineering plastic with outstanding impact resistance, good creep resistance and dimensional stability, heat resistance, low water absorption, non-toxic and excellent dielectric properties. It is the only product with good transparency among the five engineering plastics, and it is also the general engineering plastic with the fastest growth rate in recent years.

PC's three application areas are glass assembly industry, automobile industry and electronics, electrical industry, followed by industrial machinery parts, optical discs, packaging, computers and other office equipment, medical and health care, film, leisure and protective equipment. PC can be used as Windows and doors glass, PC laminate is widely used in banks, embassies, detention centers and public places of protective Windows, used for aircraft cabin cover, lighting equipment, industrial safety plate and bulletproof glass. PC board can do all kinds of signs, such as gasoline pump dial, car dashboard, warehouse and open commercial signs, point sliding indicator, PC resin for car camera system, dashboard system and interior decoration system, used as a front lampshade, with reinforced car front and rear gear plate, reflective frame, Door frame sleeve, operating rod sheath, choke plate, PC are used as junction box, socket, plug and sleeve, gasket, TV conversion device, telephone line bracket under the communication cable connector, electrical gate box, telephone switchboard components, relay shell, PC can be used as low-load parts, for household appliances motor, vacuum cleaner, Shampooer, coffee machine, toaster, power tool handle, all kinds of gears, worm gear, shaft sleeve, guide gauge, refrigerator shelf.
