Sheffield Plastics Polycarbonate Sheeting offer high impact strength

Polycarbonate products have a great blend of helpful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a sturdy material. Although it features significant impact-resistance, it's got low scratch-resistance and thus a hard coating can be applied to polycarbonate eye wear lenses and polycarbonate exterior vehicle equipment. The properties relating to polycarbonate tend to be comparable to those of Acrylic PMMA materials, although polycarbonate is undoubtedly 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 gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at high temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo large shape changes without cracking or breaking. As a result, for small changes in shape, it can be processed and formed   at room temperature using sheet metal techniques, for example forming bends with a brake. For even 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 important, which cannot be produced from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and cannot be bent unless it is heated.
Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant see through or lighting applications that would normally be thought of as requiring 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 visors for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly made out of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
