Sheffield Plastics Polycarbonate Sheet are considered unbreakable
Polycarbonate materials offer a unique balance of beneficial features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a high quality material. Though it has higher impact-resistance, it has a lower scratch-resistance and so a hard coating is often applied to polycarbonate eye protection and polycarbonate exterior automobile equipment. The characteristics of polycarbonate are generally similar to that of those of polymethyl methacrylate (PMMA, acrylic), although 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 several types of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) for making strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. Due to this fact, it may be processed and formed without needing to be heated using standard sheet metal techniques, such as forming bends on a brake. Even for 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 crucial, which may not be made from sheet metal. Understand that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and cannot be bent without heating.
Polycarbonate is frequently found in eye protection, as well as in other projectile-resistant optical type applications that would normally indicate the use of glass, but require greater impact-resistance. Many kinds of lenses are manufactured 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 manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
