Sheffield Plastics Polycarbonate Sheet offer high impact strength

Polycarbonate materials offer a unique balance of helpful features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is a very long-lasting material. Although it has high impact-resistance, it's got reduced scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior auto components. The properties of polycarbonate are similar to those of polymethyl methacrylate (PMMA, acrylic), 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 has better light transmission characteristics than several types of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools need to be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. For that reason, it is sometimes processed and formed   without needing to be heated using sheet metal techniques, which include forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which can't be created from sheet metal. Be aware that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it's brittle and cannot be bent with out a heating process.
Polycarbonate is often utilized in eye protection, along with other projectile-resistant see through or lighting applications that would normally require the use of glass, but require much greater impact-resistance. Several 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 normally made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
