Lexan Polycarbonate Flat Sheet offer high impact strength
Bayer Makrolon Polycarbonate products give you a unique balance of beneficial features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is a very high quality material. Though it has exceptional impact-resistance, it possesses lower scratch-resistance and thus a hard coating could be applied to polycarbonate eye protection and polycarbonate exterior vehicle equipment. The characteristics of polycarbonate are generally along the lines of those of polymethyl methacrylate (PMMA, acrylic), 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 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 gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at higher temperatures, generally above 80 °C (176 °F) for making strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo large shape changes without breaking or cracking. Because of that, it can be processed and formed at room temperature using sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are necessary, which can not be made from sheet metal. Be aware that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and can't be bent at room temperature.
The light weight of polycarbonate, as opposed to glass, has led to continuing development of electronic touch screens that replace 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 still generally require glass for its higher melting temperature and the ability to be etched with finer detail.
Other types of items produced from 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 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 could be needed. This either can be a coating (e.g. for improved abrasion resistance), or as a 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, the pelletized resin is heated until they melt in to a thick liquid. This liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
