Polycarbonate plastic materials give you a unique balance of useful features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is a very sturdy material. Although it features very high impact-resistance, it's got minimal scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear as well as polycarbonate exterior motor vehicle components. The properties of polycarbonate tend to be like those of polymethyl methacrylate (PMMA, acrylic), yet , 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 it has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. Hence, for small changes in shape, it can be processed and formed at room temperature 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 attractive prototyping applications where transparent or electrically non-conductive parts are essential, which cannot be produced from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and cannot be bent without heating.
Polycarbonate is commonly used in eye protection, and also in other projectile-resistant see through applications that would normally indicate the use of glass, but require greater impact-resistance. Many kinds of lenses are made of 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 manufactured from polycarbonate, such as for motorcycles, ATVs, golf carts, and small planes and helicopters.

Bayer Makrolon Polycarbonate Sheets offering light weight and break resistance
Polycarbonate materials have a great blend of helpful features which include temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a rugged material. Whilst it offers considerable impact-resistance, it possesses low scratch-resistance and so a hard coating typically is applied to polycarbonate eye wear and polycarbonate exterior auto equipment. The characteristics of polycarbonate are generally similar to that of those of polymethyl methacrylate (PMMA, acrylic), and yet 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 has better light transmission characteristics than many kinds of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at warm to high temperatures, generally above 80 °C (176 °F) to help make strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo large shape changes without breaking or cracking. Hence, it can be processed and formed without needing to be heated using sheet metal techniques, for example forming bends on a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are essential, which can not be crafted from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it's brittle and cannot be bent with out a heating process.
The light weight of polycarbonate, in contrast to glass, has led to growth and development of electronic display screens that replace glass materials with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink as well as LCD screens, though CRT, plasma screen and other LCD technologies still generally require glass for its higher melting temperature and the ability to be etched with finer detail.
Other kinds of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and blender jars. Many toys and hobby items are constructed from polycarbonate parts, e.g. fins, gyro mounts, and flybar locks for use with radio-controlled helicopters.
For use in applications exposed to weathering or UV-radiation, a special surface treatment is needed. This either can be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that begins as a solid material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is heated until they begin to melt. This liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
