Covestro Makrolon Polycarbonate Sheeting offer high impact strength
Bayer Makrolon Polycarbonate materials have a unique balance of beneficial features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is a very durable material. Whilst it features outstanding impact-resistance, it has minimal scratch-resistance and thus a hard coating can be applied to polycarbonate eye wear as well as polycarbonate exterior automotive components. The characteristics of polycarbonate are similar those of Acrylic PMMA materials, although 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 of approximately 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. For this reason, it could be processed and formed cold using sheet metal techniques, which include forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are crucial, which may not be crafted from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is 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 or lighting applications that would normally be thought of as requiring the use of glass, but require much higher impact-resistance. Many kinds of lenses are created from polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety goggles for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are typically fabricated from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
