Polycarbonate (PC) is a molecular chain containing carbonate base polymer, according to the structure of the ester base can be divided into aliphatic, aromatic, aliphatic, aromatic, and other types. Because of aliphatic and mechanical properties of aliphatic and aromatic polycarbonate is low, which limits its application in the field of engineering plastics. There are only aromatic polycarbonate won the industrialized production. Due to the particularity of polycarbonate structure, has become the fastest growing in the five engineering plastics of general engineering plastics.
Feature:
PC is characterized by high transparency, high impact resistance, high hardness, high creep-resistance, excellent dimensional stability, good resistance to low-temperature and heat, flame retardance, ease to process, and excellent sound insulation.
