Sheffield Plastics Polycarbonate Sheet are considered unbreakable
Polycarbonate plastic products offer a great blend of useful features including temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is a very rugged material. Whilst it has greater impact-resistance, it has reduced scratch-resistance and thus a hard coating could be applied to polycarbonate eyewear lenses and polycarbonate exterior motor vehicle equipment. The characteristics of polycarbonate tend to be similar to that of those of common Acrylic materials, although polycarbonate is 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 many different types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to 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 changes in basic shape without cracking. Hence, it is sometimes processed and formed at room temperature using sheet metal techniques, for example 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 required, which can't be crafted from sheet metal. Remember that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is commonly utilized in eye protection, along with other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Several types of lenses are produced 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 produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
