Lexan Polycarbonate Sheeting offer high impact strength
Polycarbonate materials have a unique balance of beneficial features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a rugged material. Whilst it features tremendous impact-resistance, it possesses reduced scratch-resistance and so a hard coating is applied to polycarbonate eyewear and polycarbonate exterior automobile equipment. The properties associated with polycarbonate are generally comparable to those of Acrylic PMMA materials, although polycarbonate is always 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 different types 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 should be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic shape changes without breaking. Due to this fact, it can be processed and formed cold using sheet metal techniques, such as forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which should not be crafted from sheet metal. Note that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and can't be bent at room temperature.
Polycarbonate is commonly utilized 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. Many different types of lenses are produced from 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 normally made up of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
