Bayer Makrolon Polycarbonate Sheets offering light weight and break resistance
Polycarbonate materials offer a balance of beneficial features including temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a long-lasting material. Whilst it offers higher impact-resistance, it has got low scratch-resistance and thus a hard coating could be applied to polycarbonate eye wear lenses as well as polycarbonate exterior automobile equipment. The properties of polycarbonate are generally along the lines of those of Acrylic PMMA materials, but 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 kinds of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without breaking or cracking. Because of that, it could be processed and formed without needing to be heated using sheet metal techniques, such as forming bends on a brake. For even sharp angle bends having 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 can't be created from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and can't be bent without heating.
Polycarbonate is often used in eye protection, as well as in other projectile-resistant see through applications that would normally require the use of glass, but require greater impact-resistance. Several types of lenses are manufactured 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 out of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
