Bayer Makrolon Polycarbonate Sheets are considered unbreakable
Bayer Makrolon Polycarbonate materials offer a balance of beneficial features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a rugged material. Even though it offers significant impact-resistance, it has minimal scratch-resistance and thus a hard coating is applied to polycarbonate eye wear lenses as well as polycarbonate exterior automotive components. The characteristics of polycarbonate are generally comparable to those of Acrylic PMMA materials, although 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 several types of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and stress-free products.
Unlike many thermoplastics, polycarbonate can undergo massive shape changes without cracking. As a result, it is sometimes processed and formed cold using sheet metal techniques, such as forming bends with a brake. For even sharp angle bends with 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 made from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and cannot be bent unless it is heated.
The light weight of polycarbonate, unlike glass, has led to growth and development of electronic touch screens that replace the traditional glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and many 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 in finer detail.
Other kinds of items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and 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 subjected to weathering or UV-radiation, a special surface treatment is needed. This can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, the pelletized resin is heated until they begin to melt. The liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to form a finished product , all in just a minute or so.
