Bayer Makrolon Polycarbonate Flat Sheet offering light weight and break resistance
Makrolon Polycarbonate products have a great blend of helpful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is a very high quality material. Whilst it features tremendous impact-resistance, it possesses lower scratch-resistance and thus a hard coating could be applied to polycarbonate eyewear lenses as well as polycarbonate exterior motor vehicle components. The properties relating to polycarbonate tend to be along the lines of those of polymethyl methacrylate (PMMA, acrylic), except 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 many different types of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at warm to high temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo large shape changes without breaking. Due to this fact, it is sometimes processed and formed at room temperature using standard sheet metal techniques, such as forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are essential, which can not be created from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and cannot be bent with out a heating process.
The light weight of polycarbonate, unlike glass, has led to growth and development of electronic view screens that replace 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 do require glass for its higher melting temperature and the ability to be etched in finer detail.
Other types of items made out of 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 out 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 maybe needed. This may be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that at the beginning, starts as a solid material in the form of small pellets. In a manufacturing process called injection molding, the pellets are heated until they melt. The melted liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
