Bayer Makrolon Polycarbonate Sheet are clear and tough
Makrolon Polycarbonate materials have a balance of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is a very long-lasting material. Although it offers very high impact-resistance, it has got minimal scratch-resistance and so a hard coating is applied to polycarbonate eye wear lenses and polycarbonate exterior automotive equipment. The characteristics associated with polycarbonate tend to be similar those of common Acrylic materials, and yet polycarbonate is undoubtedly 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 several types of glass.
Polycarbonate has a glass transition temperature of about 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large deformations without cracking or breaking. As a result, it is sometimes processed and formed cold using standard sheet metal techniques, such as forming bends on 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 necessary, which can not be made from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it's brittle and can't be bent without heating.
The light weight of polycarbonate, compared to glass, has led to growth and development of electronic touch screens that replace glass materials 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 generally still require glass for its higher melting temperature and the ability to be etched in finer detail.
Other kinds of items created from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and blender jars. Many toys and hobby items are constructed 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 perhaps the coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that begins as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is 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.
