Lexan Polycarbonate Flat Sheet offer high impact strength
Bayer Makrolon Polycarbonate products give you a unique balance of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a high quality material. Whilst it has outstanding impact-resistance, it possesses low scratch-resistance and so a hard coating is applied to polycarbonate eyewear and polycarbonate exterior automotive equipment. The properties relating to polycarbonate are generally along the lines of those of Acrylic PMMA materials, except 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 many kinds of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), as a result 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 stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large deformations without cracking. Therefore, it may be processed and formed at room temperature using standard 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 attractive 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 is brittle and cannot be bent unless it is heated.
The light weight of polycarbonate, compared with glass, has led to continuing development of electronic display screens that replace glass materials with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and some 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 with finer detail.
Other kinds of items made out of Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and common style blender jars. Many toys and hobby products are made out 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 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. This liquid polycarbonate is then rapidly injected into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to create a finished product , all in just a minute or so.
