Covestro Makrolon Polycarbonate Sheeting are clear and tough
Bayer Makrolon Polycarbonate products have a great blend of beneficial features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a sturdy material. Though it has significant impact-resistance, it's got lower scratch-resistance and so a hard coating could be applied to polycarbonate eye wear and polycarbonate exterior vehicle equipment. The properties relating to polycarbonate tend to be similar to that of 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 most grades of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking. Subsequently, for small changes in shape, it can be processed and formed without needing to be heated using sheet metal techniques, for example forming bends with a brake. For even 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 needed, which can't be created from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and can't be bent with out a heating process.
The light weight of polycarbonate, compared to glass, has led to advancement of electronic view screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and some 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 with finer detail.
Other types 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 goods are made from polycarbonate parts, e.g. fins, gyro mounts, and flybar locks for use with radio-controlled helicopters.
For use in applications exposed to weathering or UV-radiation, a special surface treatment is needed. This may be a coating (e.g. for improved abrasion resistance), or as 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, these small pellets are heated until they melt. This liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
