Bayer Makrolon Polycarbonate products have a great blend of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a rugged material. Although it offers very high impact-resistance, it possesses a lower scratch-resistance and thus a hard coating could be applied to polycarbonate eyeglasses lenses and polycarbonate exterior automobile components. The characteristics associated with polycarbonate tend to be similar to that of those of common Acrylic materials, although polycarbonate 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 has better light transmission characteristics than several types 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 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 almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without breaking or cracking. For this reason, it can be processed and formed cold using sheet metal techniques, which include forming bends with 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 required, which cannot be made from sheet metal. Be aware that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it 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 view screens that replace the traditional glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and several 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 types of items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and common style blender jars. Many toys and hobby items are made 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 maybe needed. This may be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that at the beginning, starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, the pellets are heated until they melt. The liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
