Bayer Makrolon Polycarbonate Flat Sheet are clear and tough
Bayer Makrolon Polycarbonate products have a balance of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a long-lasting material. Whilst it features higher impact-resistance, it possesses lower scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear lenses and polycarbonate exterior automobile components. The properties relating to polycarbonate tend to be similar to that of those of common Acrylic materials, but polycarbonate is going to be 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 many kinds of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at high temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo massive shape changes without cracking. Hence, it can be processed and formed at room temperature using standard sheet metal techniques, for instance 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 needed, which may not be made from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and can't be bent at room temperature.
The light weight of polycarbonate, as opposed to glass, has led to advancement 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 its ability to be etched in finer detail.
Other miscellaneous 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 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 could be needed. This may be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
The 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 begin to melt. The melted liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
