Polycarbonate is easily worked, moulded, and thermoformed. Its unique features such as impact resistant, temperature resistant and optical properties made it position between commodity plastics and engineering plastics.
PC is commonly used in eyeglass lenses, safety glasses, drinking bottles, and DVDs. Mostly for its clarity, durability and light weight features.
Gin Wei’s PC contains some percentage of PMMA which reduces the MI, impact resistance and clarity.
Gin Wei’s PC+PMMA is most suitable for advertisement boards. |
