Lexan Polycarbonate Sheets offering light weight and break resistance
Polycarbonate products give you a balance of helpful features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a long-lasting material. Although it offers outstanding impact-resistance, it has got low scratch-resistance and so a hard coating may be applied to polycarbonate eye protection lenses as well as polycarbonate exterior motor vehicle components. The characteristics relating to polycarbonate tend to be along the lines of those of polymethyl methacrylate (PMMA, acrylic), yet , polycarbonate 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 has better light transmission characteristics than several types of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), in order that it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at higher temperatures, generally above 80 °C (176 °F) in order to make strain- and stress-free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic shape changes without cracking. Therefore, it may be processed and formed without needing to be heated using 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 useful for prototyping applications where transparent or electrically non-conductive parts are essential, which cannot be created from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and can't be bent with out a heating process.
The light weight of polycarbonate, in contrast to glass, has led to growth and development of electronic view screens that replace glass materials 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 which still require glass for its higher melting temperature and the ability to be etched with finer detail.
Other miscellaneous 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 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 perhaps the coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that starts as a solid material in the form of small pellets. In a manufacturing process called injection molding, the pellets are heated until they melt. The melted liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to create a finished product in a matter of minutes.
