Bayer Makrolon Polycarbonate Sheeting are considered unbreakable
Polycarbonate plastic materials give you a unique balance of beneficial features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is a very durable material. Though it features outstanding impact-resistance, it has minimal scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear and polycarbonate exterior auto components. The properties of polycarbonate are similar to those of polymethyl methacrylate (PMMA, acrylic), but 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 has a glass transition temperature of approximately 150 °C (302 °F), so 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 make strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic deformations without cracking. Because of this, it could be processed and formed at room temperature using sheet metal techniques, for example forming bends on a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are important, which should not be made from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and cannot be bent unless it is heated.
The light weight of polycarbonate, compared to glass, has led to development of electronic view screens that replace the traditional 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 still generally require glass for its higher melting temperature and its ability to be etched in finer detail.
Other types of items made out of Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby items are made of 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 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 at the beginning, starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, these small pellets are heated until they melt and become a very thick liquid. The melted liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to create a finished product , all in just a minute or so.
