Bayer Makrolon Polycarbonate products offer a balance of useful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very rugged material. Even though it features high impact-resistance, it's got minimal scratch-resistance and so a hard coating could be applied to polycarbonate eyeglasses as well as polycarbonate exterior automobile equipment. The characteristics of polycarbonate are like those of polymethyl methacrylate (PMMA, acrylic), except 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 has better light transmission characteristics than several types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo massive deformations without cracking. For that reason, it could be processed and formed without needing to be heated using sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are important, which cannot be created from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in looks to polycarbonate, but is brittle and can't be bent unless it is heated.
The light weight of polycarbonate, compared with glass, has led to advancement 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 which still require glass for its higher melting temperature and its ability to be etched in finer detail.
Other miscellaneous items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, 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 subjected to weathering or UV-radiation, a special surface treatment is 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 starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, these small pellets are heated until they melt. The 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 less than a minute.
