PC (Polycarbonate) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates received their name because they are polymers containing carbonate groups. A balance of useful features, including temperature resistance, impact resistance and optical properties, positions polycarbonates between commodity plastics and engineering plastics.
Stock Shape / Size Range : Plate (Thickness: 1mm – 100mm) / Rod (Dia: 3mm – 250mm) / Tube (4mm – 505mm)
Areas in which high transparency and mechanical characteristics such as impact strength, strength and dimensional stability are key, such as electrical and apparatus components, CDs and DVDs. Spectacle lenses and optical lenses, lamp covers, viewing windows used in food technology. Also lenses for car headlamps, aircraft windows, underwater housings for cameras, conservatory and packaging, Also suitable as a housing material for cameras, mobile phones, and laptops etc.
