Sheffield Plastics Polycarbonate Flat Sheet offering light weight and break resistance
Makrolon Polycarbonate materials have a balance of beneficial features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a high quality material. Even though it offers extraordinary impact-resistance, it's got low scratch-resistance and so a hard coating may be applied to polycarbonate eye protection lenses as well as polycarbonate exterior automobile components. The properties relating to polycarbonate are comparable to those of polymethyl methacrylate (PMMA, acrylic), except polycarbonate definitely 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 has better light transmission characteristics than many different types of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools are required to be held at higher temperatures, generally above 80 °C (176 °F) to produce strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking. For that reason, it may be processed and formed at room temperature using sheet metal techniques, which include forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which cannot be produced from sheet metal. Note that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and cannot be bent unless it is heated.
Polycarbonate is frequently used in eye protection, and also in other projectile-resistant see through or lighting applications that would normally be thought of as requiring the use of glass, but require greater impact-resistance. Many different 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 typically made from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
