Makrolon Polycarbonate materials offer a balance of beneficial features which include temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials. Polycarbonate is a very long-lasting material. Though it offers considerable impact-resistance, it has a lower scratch-resistance and so a hard coating is applied to polycarbonate eye protection lenses and polycarbonate exterior motor vehicle components. The properties relating to polycarbonate are generally along the lines of those of polymethyl methacrylate (PMMA, acrylic), but polycarbonate definitely is 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 several types of glass. Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), in order that it softens slowly above this point and ...
