Polycarbonate continued
Polycarbonate is a broadly used engineering grade thermoplastic. Polycarbonate is easily Injection molded, Extruded or thermoformed; as such, Polycarbonate is widely used especially in applications where any of its main features - high impact resistance, temperature resistance, or excellent clarity - are required.
Examples of uses include: Safety glasses, Automotive lenses, fuses & conncetors, Computer housings, Medical device, Food contact applications.
