Sheffield Plastics Polycarbonate Flat Sheet are considered unbreakable
Polycarbonate materials offer a unique balance of beneficial features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a sturdy material. Although it has exceptional impact-resistance, it possesses low scratch-resistance and thus a hard coating is applied to polycarbonate eye protection lenses as well as polycarbonate exterior auto components. The properties of polycarbonate are generally comparable to those of Acrylic PMMA materials, yet , 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 it has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) to make strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic deformations without cracking or breaking. Subsequently, it could be processed and formed at room temperature using standard sheet metal techniques, for instance 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 cannot be produced from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and cannot be bent at room temperature.
Polycarbonate is commonly found in eye protection, along with other projectile-resistant optical type applications that would normally be thought of as requiring the use of glass, but require 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 commonly made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
