Polycarbonates (PC), known by the trademarked names Lexan, Makrolon and others, are a particular group of thermoplastic polymers. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications.
Polycarbonates do not have a unique resin identification code and are identified as Other, 7. Items made from polycarbonate can contain the precursor monomer bisphenol A (BPA).
Structure of polycarbonate:
Polycarbonates received their name because they are polymers containing carbonate groups (–O–(C=O)–O–). A balance of useful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
