Sheffield Plastics Polycarbonate Sheeting offer high impact strength

Makrolon Polycarbonate products have a unique balance of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very sturdy material. Although it has very high impact-resistance, it's got a lower scratch-resistance and so a hard coating can be applied to polycarbonate eye wear as well as polycarbonate exterior motor vehicle equipment. The characteristics relating to polycarbonate are like those of polymethyl methacrylate (PMMA, acrylic), yet , 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 many different types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), therefore it softens gradually 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 produce strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo massive deformations without cracking or breaking. Subsequently, it may be processed and formed   without needing to be heated using sheet metal techniques, which include forming bends on a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which can't be crafted from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in looks to polycarbonate, but it's brittle and can't be bent at room temperature.
Polycarbonate is often utilized in eye protection, and also in other projectile-resistant optical type applications that would normally indicate 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 goggles for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are normally produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
