Lexan Polycarbonate Sheets offering light weight and break resistance
Bayer Makrolon Polycarbonate products have a unique balance of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is definitely a rugged material. Although it offers greater impact-resistance, it has got lower scratch-resistance and thus a hard coating typically is applied to polycarbonate eye protection as well as polycarbonate exterior vehicle equipment. The characteristics of polycarbonate are generally along the lines of those of Acrylic PMMA materials, but polycarbonate is 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 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 are required to be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo massive deformations without breaking or cracking. Because of that, it could be processed and formed cold using sheet metal techniques, such as forming bends on a brake. For even 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 essential, which should not be produced from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it is brittle and cannot be bent unless it is heated.
Polycarbonate is frequently utilized in eye protection, as well as in other projectile-resistant optical type applications that would normally indicate the use of glass, but require higher impact-resistance. Many different types of lenses are produced 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 fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
