Sheffield Plastics Polycarbonate Flat Sheet are considered unbreakable
Makrolon Polycarbonate products have a unique balance of beneficial features including temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials. Polycarbonate is a very tough material. Though it features significant impact-resistance, it's got low scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses as well as polycarbonate exterior auto components. The characteristics associated with polycarbonate are generally similar to those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate is always stronger, it is usable in a wider temperature range and is a bit more expensive. This plastic polymer is highly transparent to visible light and it has better light transmission characteristics than many different types of glass. Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), so it softens slowly above this point and ...
