Bayer Makrolon Polycarbonate materials have a balance of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a durable material. Though it has very high impact-resistance, it has got a lower scratch-resistance and so a hard coating can be applied to polycarbonate eye protection lenses and polycarbonate exterior auto equipment. The properties relating to polycarbonate are along the lines of those of common Acrylic materials, but 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 different types of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools need to be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo large shape changes without breaking or cracking. Because of that, for small changes in shape, it can be processed and formed cold using standard sheet metal techniques, for instance forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are needed, which can't be made from sheet metal. Understand that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and cannot be bent at room temperature.
The light weight of polycarbonate, compared with glass, has led to growth and development of electronic view screens that replace glass materials with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and a few LCD screens, though CRT, plasma screen and other LCD technologies generally still require glass for its higher melting temperature and the ability to be etched with finer detail.
Other kinds of items created 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 products 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 could be needed. This can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
The 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. The melted liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to form a finished product in less than a minute.
