Bayer Makrolon Polycarbonate Sheet are considered unbreakable
Bayer Makrolon Polycarbonate materials give you a balance of useful features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering materials.
Polycarbonate is a very high quality material. Whilst it has considerable impact-resistance, it has reduced scratch-resistance and so a hard coating can be applied to polycarbonate eye wear lenses and polycarbonate exterior motor vehicle components. The characteristics relating to polycarbonate are generally along the lines of those of Acrylic PMMA materials, yet , polycarbonate definitely 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 it has better light transmission characteristics than several types of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), in order that it softens slowly 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 reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic changes in basic shape without cracking. Due to this fact, it is sometimes processed and formed at room temperature using standard sheet metal techniques, for example forming bends with a brake. Even for 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 essential, which may not be made from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and cannot be bent unless it is heated.
The light weight of polycarbonate, compared to glass, has led to 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 as well as LCD screens, though CRT, plasma screen and other LCD technologies which still do require glass for its higher melting temperature and the ability to be etched with finer detail.
Other kinds of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby products are produced 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 either can be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
The 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, this pellet material is heated until they melt in to a thick liquid. This liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to form a finished product in less than a minute.
