Covestro Makrolon Polycarbonate Sheeting are clear and tough
Polycarbonate plastic materials offer a balance of helpful features including high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very sturdy material. Even though it offers outstanding impact-resistance, it has got low scratch-resistance and so a hard coating may be applied to polycarbonate eyeglasses as well as polycarbonate exterior vehicle equipment. The properties associated with polycarbonate are along the lines of those of polymethyl methacrylate (PMMA, acrylic), although polycarbonate is actually 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 has a glass transition temperature of about 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at warm to high temperatures, generally above 80 °C (176 °F) for making strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo large deformations without cracking or breaking. For this reason, it can be processed and formed without needing to be heated using sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends having 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 can not be crafted from sheet metal. Note that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it is brittle and cannot be bent unless it is heated.
Polycarbonate is frequently used in eye protection, in addition to other projectile-resistant see through applications that would normally indicate the use of glass, but require much higher impact-resistance. Many different types of lenses are created from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally made of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
