Sheffield Plastics Polycarbonate Flat Sheet offering light weight and break resistance

Makrolon Polycarbonate products have a balance of useful features which include high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a sturdy material. Even though it features very high impact-resistance, it possesses reduced scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses and polycarbonate exterior automotive components. The characteristics associated with polycarbonate are along the lines of those of polymethyl methacrylate (PMMA, acrylic), 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 has better light transmission characteristics than several types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), therefore it softens gradually 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 with making strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo large changes in basic shape without breaking or cracking. Because of this, it can be processed and formed   without needing to be heated using standard sheet metal techniques, for instance forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are required, which cannot be created from sheet metal. Keep in mind that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and can't be bent unless it is heated.

The light weight of polycarbonate, as opposed 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 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 in finer detail.
Other types of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby items are made 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 could be needed. This can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that begins as a solid material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is heated until they melt. This liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
