Makrolon Polycarbonate products offer a balance of beneficial features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a sturdy material. Whilst it has outstanding impact-resistance, it has reduced scratch-resistance and so a hard coating can be applied to polycarbonate eye protection lenses as well as polycarbonate exterior automobile equipment. The properties relating to polycarbonate are along the lines of those of Acrylic PMMA materials, and yet polycarbonate is going to be 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 has a glass transition temperature near 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo large changes in basic shape without breaking. For that reason, for small changes in shape, it can be processed and formed at room temperature using sheet metal techniques, such as forming bends with a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are essential, which can't be crafted from sheet metal. Be aware that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and can't be bent unless it is heated.
Polycarbonate is commonly utilized in eye protection, as well as in other projectile-resistant optical type applications that would normally be thought of as requiring the use of glass, but require much greater impact-resistance. Several types of lenses are created 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 typically produced from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
