Bayer Makrolon Polycarbonate Flat Sheet offer high impact strength
Polycarbonate plastic products have a balance of useful features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is a very rugged material. Even though it has considerable impact-resistance, it's got low scratch-resistance and so a hard coating can be applied to polycarbonate eye wear lenses as well as polycarbonate exterior automotive components. The characteristics of polycarbonate are comparable to those of Acrylic PMMA materials, but 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 most grades of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), in order that 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) to help make strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without breaking. Therefore, it is sometimes processed and formed without needing to be heated using standard sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are essential, which cannot be crafted from sheet metal. Understand that PMMA/Plexiglas, that is similar in looks to polycarbonate, but is brittle and cannot be bent at room temperature.
Polycarbonate is commonly used in eye protection, along with other projectile-resistant viewing and lighting applications that would normally require the use of glass, but require 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 commonly manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
