What is polycarbonate?
The term Polycarbonate describes a polymer which is composed of many (“poly”) identical units of bisphenol A connected by carbonate-linkages in its backbone chain. Chemically, a carbonate group is a di-ester of carbonic acid, the result of which is a polymeric chain. Polycarbonate is transformed into the required shape by melting it and forcing it under pressure into a mould or die. There are two dominant processes involved in making products from polycarbonate:
Extrusion : The polymer melt is continuously pressed through an orifice called a “die”, which gives the molten polymer its final shape. This process makes it possible to create infinitely long pipes, profiles or sheets.
