Covestro Makrolon Polycarbonate Flat Sheet offer high impact strength
Bayer Makrolon Polycarbonate products offer a great blend of helpful features which include temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is a very sturdy material. Whilst it has very high impact-resistance, it's got a lower scratch-resistance and thus a hard coating is often applied to polycarbonate eye wear and polycarbonate exterior vehicle components. The properties associated with polycarbonate tend to be along the lines of those of Acrylic PMMA materials, 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 many different types of glass.
Polycarbonate has a glass transition temperature of about 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 make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large shape changes without breaking. For that reason, for small changes in shape, it can be processed and formed without needing to be heated using 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 useful for prototyping applications where transparent or electrically non-conductive parts are essential, which may not be made from sheet metal. Keep in mind that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and can't be bent with out a heating process.
Polycarbonate is often utilized in eye protection, and also in other projectile-resistant see through applications that would normally require the use of glass, but require greater 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 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.
