Lexan Polycarbonate Flat Sheet offer high impact strength
Bayer Makrolon Polycarbonate materials give you a balance of beneficial features which include high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is a very durable material. Whilst it offers outstanding impact-resistance, it's got minimal scratch-resistance and thus a hard coating is often applied to polycarbonate eye wear as well as polycarbonate exterior vehicle equipment. The characteristics relating to polycarbonate are along the lines of those of Acrylic PMMA materials, although 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 has better light transmission characteristics than many different types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo massive shape changes without cracking or breaking. As a result, it may be processed and formed without needing to be heated using standard sheet metal techniques, which include forming bends with a brake. For even sharp angle bends having 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 can not be made from sheet metal. Note that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and can't be bent at room temperature.
The light weight of polycarbonate, compared with glass, has led to continuing 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 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 with finer detail.
Other types of items made out of Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and common style blender jars. Many toys and hobby items 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 maybe needed. This may be a coating (e.g. for improved abrasion resistance), or a 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 begin to melt. The melted liquid polycarbonate is then rapidly pushed into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
