Sheffield Plastics Polycarbonate Sheets are clear and tough
Makrolon Polycarbonate products give you a unique balance of useful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a sturdy material. Although it features tremendous impact-resistance, it has got low scratch-resistance and so a hard coating is applied to polycarbonate eye wear lenses and polycarbonate exterior auto equipment. The characteristics associated with polycarbonate are similar to that of those of polymethyl methacrylate (PMMA, acrylic), 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 it has better light transmission characteristics than many different types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at higher temperatures, generally above 80 °C (176 °F) to produce strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without breaking. Hence, it may be processed and formed without needing to be heated using sheet metal techniques, for instance forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are necessary, which can not be made from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and cannot be bent without heating.
Polycarbonate is frequently found in eye protection, as well as in other projectile-resistant see through applications that would normally be thought of as requiring the use of glass, but require greater impact-resistance. Many kinds 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 normally made out of polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.
