Sheffield Plastics Polycarbonate Flat Sheet offering light weight and break resistance

Polycarbonate plastic materials have a balance of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering materials.
Polycarbonate is definitely a high quality material. Although it offers increased impact-resistance, it has got a lower scratch-resistance and so a hard coating is often applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior vehicle components. The properties associated with polycarbonate tend to be like those of Acrylic PMMA 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 several types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at warm to high temperatures, generally above 80 °C (176 °F) to help make strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. Subsequently, it may be processed and formed   at room temperature using sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are needed, which can not be made from sheet metal. Keep in mind that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and can't be bent without heating.

The light weight of polycarbonate, in contrast to glass, has led to advancement of electronic display 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 which still do require glass for its higher melting temperature and its 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 goods are made out of 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 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 begin to melt. The liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to produce a finished product , all in just a minute or so.
