Bayer Makrolon Polycarbonate Flat Sheet offering light weight and break resistance
Bayer Makrolon Polycarbonate materials give you a unique balance of beneficial features including high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a sturdy material. Although it offers high impact-resistance, it has got low scratch-resistance and thus a hard coating is applied to polycarbonate eyewear and polycarbonate exterior motor vehicle equipment. The characteristics of polycarbonate are similar to those of Acrylic PMMA materials, but polycarbonate is definitely 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 most grades of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic deformations without breaking. Subsequently, for small changes in shape, it can be processed and formed  without needing to be heated using sheet metal techniques, such as forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are necessary, which can't be created from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and can't be bent with out a heating process.
The light weight of polycarbonate, in contrast to glass, has led to development of electronic display screens that replace the traditional 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 which still do require glass for its higher melting temperature and its ability to be etched with finer detail.
Other types of items fabricated from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and common style blender jars. Many toys and hobby items are produced 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 either can be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
Bayer 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 melt in to a thick liquid. This liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to create a finished product , that only takes about a minute to complete.
