Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. A balance of useful features, including temperature resistance, impact resistance and optical properties, positions polycarbonates between commodity plastics and engineering plastics.
The main polycarbonate material is produced by the reaction of biphenyl A (BPA) and phosgene COCl2.
Polycarbonate is mainly used for electronic applications that capitalize on its collective safety features. The second largest consumer of polycarbonates is the construction industry, e.g. for dome lights, flat or curved glazing, and sound walls.Other applications of polycarbonate are the production of Compact Discs, DVDs and Blu-ray Discs,Miscellaneous items include durable, lightweight luggage, MP3/digital audio player cases, ocarinas, computer cases, toys, etc…
