Sheffield Plastics Polycarbonate Flat Sheet offer high impact strength
Polycarbonate products give you a great blend of helpful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a rugged material. Though it offers greater impact-resistance, it's got a lower scratch-resistance and thus a hard coating can be applied to polycarbonate eye wear lenses as well as polycarbonate exterior vehicle components. The characteristics associated with polycarbonate are generally similar those of Acrylic PMMA materials, but 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 it has better light transmission characteristics than many kinds of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at warm to 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 deformations without breaking or cracking. Due to this fact, it is sometimes processed and formed cold using sheet metal techniques, for instance 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 important, which should not be produced from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and can't be bent at room temperature.
Polycarbonate is often found in eye protection, and also in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much greater impact-resistance. Many different 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 crafted from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
