Covestro Makrolon Polycarbonate Sheeting offering light weight and break resistance
Polycarbonate plastic products offer a great blend of useful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is a very durable material. Even though it offers considerable impact-resistance, it has got reduced scratch-resistance and thus a hard coating could be applied to polycarbonate eye wear lenses and polycarbonate exterior automotive equipment. The characteristics associated with polycarbonate are similar those of Acrylic PMMA materials, and yet polycarbonate is definitely 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 many kinds of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at high temperatures, generally above 80 °C (176 °F) for making strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo dramatic shape changes without breaking or cracking. Because of this, it may be processed and formed at room temperature using sheet metal techniques, such as forming bends on a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are essential, which cannot be created from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but is brittle and cannot be bent unless it is heated.
Polycarbonate is commonly utilized in eye protection, and also in other projectile-resistant optical type applications that would normally require the use of glass, but require much greater impact-resistance. Many kinds 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 commonly made out of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
