Bayer Makrolon Polycarbonate Sheets are clear and tough
Bayer Makrolon Polycarbonate products offer a great blend of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a long-lasting material. Even though it features considerable impact-resistance, it has got minimal scratch-resistance and so a hard coating is often applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior automobile equipment. The properties of polycarbonate are generally comparable to those of common Acrylic materials, except polycarbonate is 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 carries a glass transition temperature near 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) in order to make strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo large shape changes without breaking. Subsequently, it is sometimes processed and formed cold using sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are important, which cannot be created from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and cannot be bent with out a heating process.
The light weight of polycarbonate, compared with glass, has led to continuing development of electronic touch 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 require glass for its higher melting temperature and its ability to be etched with finer detail.
Other miscellaneous items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and common style blender jars. Many toys and hobby products 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 maybe 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, the pellets are heated until they begin to melt. This liquid polycarbonate is then rapidly pushed into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to create a finished product , all in just a minute or so.
