Lexan Polycarbonate Sheeting offering light weight and break resistance
Bayer Makrolon Polycarbonate materials offer a balance of useful features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is a very long-lasting material. Although it offers outstanding impact-resistance, it has got low scratch-resistance and so a hard coating typically is applied to polycarbonate eyeglasses lenses and polycarbonate exterior automobile components. The characteristics of polycarbonate are like those of common Acrylic materials, except 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 it has better light transmission characteristics than many different types of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), so it softens gradually 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. Because of this, it could be processed and formed without needing to be heated using sheet metal techniques, such as forming bends on a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which can not be crafted from sheet metal. Please keep in mind PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and cannot be bent with out a heating process.
The light weight of polycarbonate, compared with glass, has led to growth and development of electronic view 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 its ability to be etched with finer detail.
Other kinds of items manufactured from 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 constructed 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 can be a coating (e.g. for improved abrasion resistance), or perhaps the 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 create a finished product in less than a minute.
