Polycarbonate materials offer a great blend of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a durable material. Though it has increased impact-resistance, it has got reduced scratch-resistance and so a hard coating can be applied to polycarbonate eye wear lenses and polycarbonate exterior automotive equipment. The properties of polycarbonate are similar to those of polymethyl methacrylate (PMMA, acrylic), except polycarbonate is undoubtedly 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 carries a glass transition temperature of about 150 °C (302 °F), so 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 produce strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic deformations without cracking. Because of this, it could be processed and formed cold using sheet metal techniques, for instance forming bends with 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 needed, which should not be made from sheet metal. Be aware that PMMA/Plexiglas, which is similar in looks to polycarbonate, but is brittle and can't be bent unless it is heated.
The light weight of polycarbonate, in contrast to glass, has led to growth and development of electronic touch screens that replace the traditional glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and some LCD screens, though CRT, plasma screen and other LCD technologies which still require glass for its higher melting temperature and the ability to be etched in finer detail.
Other types of items fabricated from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and common style blender jars. Many toys and hobby goods are manufactured from polycarbonate parts, e.g. fins, gyro mounts, and flybar locks for use with radio-controlled helicopters.
For use in applications subjected to weathering or UV-radiation, a special surface treatment maybe 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 plastic 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 injected into molds, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
