Bayer Makrolon Polycarbonate Flat Sheet offer high impact strength
Polycarbonate materials offer a unique balance of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very durable material. Whilst it offers considerable impact-resistance, it has a lower scratch-resistance and thus a hard coating is applied to polycarbonate eye protection lenses and polycarbonate exterior motor vehicle equipment. The characteristics associated with polycarbonate are similar to that of those of Acrylic PMMA materials, although 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 most grades 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 need to be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo large shape changes without breaking or cracking. As a result, it can be processed and formed without needing to be heated using sheet metal techniques, such as forming bends with 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 essential, which should not be made from sheet metal. Note that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and cannot be bent at room temperature.
Polycarbonate is commonly found in eye protection, in addition to other projectile-resistant see through or lighting applications that would normally require the use of glass, but require much higher impact-resistance. Several types of lenses are made of polycarbonate, including automotive headlamp lenses, lighting lenses, sunglass/eyeglass lenses, swimming and SCUBA goggles, and safety glasses for use in sporting helmets/masks and police riot gear. Windscreens in small motorized vehicles are commonly crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
