Makrolon Polycarbonate products offer a unique balance of useful features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics. Polycarbonate is a very long-lasting material. Although it features considerable impact-resistance, it's got minimal scratch-resistance and thus a hard coating is applied to polycarbonate eyewear lenses and polycarbonate exterior motor vehicle equipment. The properties relating to polycarbonate are generally comparable to those of common Acrylic materials, although polycarbonate 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 most grades of glass. Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), as a result it softens gradually above this point and flows above about 3...
