Bayer Makrolon Polycarbonate Flat Sheet are clear and tough
Polycarbonate plastic products have a balance of useful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a tough material. Even though it offers exceptional impact-resistance, it has a lower scratch-resistance and thus a hard coating is often applied to polycarbonate eye protection lenses and polycarbonate exterior auto equipment. The characteristics associated with polycarbonate are generally comparable to 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 it has better light transmission characteristics than most grades of glass.
Polycarbonate has a glass transition temperature near 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 almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking. As a result, it is sometimes processed and formed at room temperature using sheet metal techniques, which include forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which cannot be created from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and cannot be bent unless it is heated.
Polycarbonate is frequently found in eye protection, in addition to other projectile-resistant see through or lighting applications that would normally indicate the use of glass, but require higher 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 goggles 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.
