Sheffield Plastics Polycarbonate Sheeting offering light weight and break resistance

Polycarbonate plastic products give you a balance of useful features including temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very sturdy material. Even though it features considerable impact-resistance, it possesses a lower scratch-resistance and so a hard coating can be applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior automotive equipment. The properties associated with polycarbonate are generally comparable to those of Acrylic PMMA materials, yet , polycarbonate is definitely 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 kinds of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), as a result 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) in order to make strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo massive deformations without breaking. Hence, it is sometimes processed and formed   cold using sheet metal techniques, such as forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are necessary, which can’t be crafted from sheet metal. Remember that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and cannot be bent without heating.
Polycarbonate is frequently used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally require the use of glass, but require much greater impact-resistance. Several types of lenses are manufactured 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 normally manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
