Polycarbonate is an organic combination of rigidity and toughness. Its light transmittance is about 90%, close to glass but lighter than glass, not brittle, and easy to process. Pure polycarbonate can pass a certain level of fire test without adding any flame retardant. With a small amount of flame retardant, polycarbonate can achieve the highest level of fire protection. Polycarbonate can be used up to 120 to 130 degrees.
Polycarbonate is a polymer having a carbonate group in a molecular chain, and can be classified into aliphatic, aromatic, aliphatic-aromatic and the like depending on the structure of the ester group. Among them, the aliphatic and aliphatic-aromatic polycarbonates have low mechanical properties, which limits their application in engineering plastics.
