Bayer Makrolon Polycarbonate Flat Sheet offer high impact strength
Polycarbonate products offer a balance of useful features including temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very durable material. Even though it offers high impact-resistance, it has got lower scratch-resistance and thus a hard coating could be applied to polycarbonate eyewear lenses as well as polycarbonate exterior auto components. The properties relating to polycarbonate are like those of polymethyl methacrylate (PMMA, acrylic), although polycarbonate is always 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 several types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools will have 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 other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. Because of this, it could be processed and formed without needing to be heated using sheet metal techniques, such as forming bends on a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which may not be made from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it's brittle and can't be bent unless it is heated.
The light weight of polycarbonate, compared to glass, has led to advancement of electronic touch screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink as well as 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 in finer detail.
Other kinds of items produced from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby goods are made 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 either can 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, the pelletized resin is heated until they melt in to a thick liquid. The melted 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.
