PC (Polycarbonate)

Polycarbonate is an amorphous material with excellent impact strength, clarity, and optical properties. It is very widely used and a wide variety of compounds are available. Polycarbonate has excellent mechanical properties, and can be molded to tight tolerances. It is attacked by solvents and petrochemicals, and its weatherability is only adequate.

Applications: Automotive Headlights, Business Machines, Consumer Products, Telecommunications, Medical Products and Mechanical Goods.
