Bayer Makrolon Polycarbonate Sheets are clear and tough
Makrolon Polycarbonate products have a unique balance of beneficial features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a durable material. Whilst it features greater impact-resistance, it's got minimal scratch-resistance and so a hard coating typically is applied to polycarbonate eyewear and polycarbonate exterior automotive components. The characteristics relating to polycarbonate are generally like those of Acrylic PMMA materials, 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 several types of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) in order to make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo massive changes in basic shape without cracking or breaking. As a result, it could be processed and formed cold using sheet metal techniques, for example forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are needed, which can't be made from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and cannot be bent without heating.
Polycarbonate is commonly found in eye protection, along with other projectile-resistant viewing and lighting applications that would normally require the use of glass, but require much greater impact-resistance. Many different types of lenses are made of 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 typically constructed from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
