Bayer Makrolon Polycarbonate Sheets offering light weight and break resistance
Bayer Makrolon Polycarbonate products offer a balance of helpful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a sturdy material. Whilst it offers increased impact-resistance, it possesses lower scratch-resistance and so a hard coating may be applied to polycarbonate eyeglasses and polycarbonate exterior automobile equipment. The characteristics of polycarbonate are like those of polymethyl methacrylate (PMMA, acrylic), except 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 several types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at higher temperatures, generally above 80 °C (176 °F) for making strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic deformations without cracking. Because of this, for small changes in shape, it can be processed and formed cold using sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which cannot be produced from sheet metal. Keep in mind that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and can't be bent without heating.
Polycarbonate is frequently utilized in eye protection, as well as in other projectile-resistant see through applications that would normally require the use of glass, but require higher impact-resistance. Many different 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 produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
