Covestro Makrolon Polycarbonate Flat Sheet offering light weight and break resistance
Polycarbonate plastic products offer a unique balance of helpful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is a very sturdy material. Even though it offers greater impact-resistance, it's got lower scratch-resistance and thus a hard coating is often applied to polycarbonate eye wear as well as polycarbonate exterior automobile components. The properties of polycarbonate are similar to those of polymethyl methacrylate (PMMA, acrylic), yet , 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 has better light transmission characteristics than most grades of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo large deformations without cracking. Because of that, it could be processed and formed cold using sheet metal techniques, for instance forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are required, which cannot be produced from sheet metal. Remember that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it's brittle and cannot be bent unless it is heated.
Polycarbonate is frequently utilized in eye protection, and also in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require higher impact-resistance. Several types of lenses are manufactured from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety glasses for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally made out of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
