PC
Polycarbonate is a polymer containing carbonate group in the molecular chain, according to the structure of the ester group can be divided into aliphatic, aromatic, aliphatic - aromatic and other types. The low mechanical properties of aliphatic and aliphatic aromatic polycarbonate limit their application in engineering plastics.
PC can also be made into a film, its high puncture resistance strength, suitable for welding, heat sealing. PC film surface tension, before printing without corona treatment, electroplating performance is good. Can be used for medicine, food packaging, and cardboard composite decorative board, etc.
