Makrolon Polycarbonate products have a balance of useful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is a very rugged material. Whilst it offers tremendous impact-resistance, it has got lower scratch-resistance and so a hard coating is often applied to polycarbonate eye wear lenses and polycarbonate exterior automobile components. The properties relating to polycarbonate tend to be like those of polymethyl methacrylate (PMMA, acrylic), yet , 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 different types of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic shape changes without breaking or cracking. Therefore, it could be processed and formed cold using standard sheet metal techniques, such as forming bends on a brake. Even for 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 needed, which may not be created from sheet metal. Understand that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it is brittle and cannot be bent without heating.
The light weight of polycarbonate, unlike 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 many 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 miscellaneous items created 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 made of 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 could be needed. This 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 starts as a solid material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is heated until they melt and become a very thick liquid. This liquid polycarbonate is then rapidly injected into a mold, compressed under high pressure and cooled to form a finished product , all in just a minute or so.
