Sheffield Plastics Polycarbonate Sheeting offering light weight and break resistance
Polycarbonate plastic materials give you a great blend of beneficial features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very long-lasting material. Though it features significant impact-resistance, it's got minimal scratch-resistance and so a hard coating may be applied to polycarbonate eye protection and polycarbonate exterior automotive components. The properties of polycarbonate tend to be similar to those of common Acrylic materials, yet , polycarbonate is going to be 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 kinds 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 must be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo massive deformations without breaking or cracking. Therefore, it can be processed and formed  without needing to be heated using standard sheet metal techniques, which include forming bends with a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are essential, which can not be created from sheet metal. Remember that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and can't be bent with out a heating process.
The light weight of polycarbonate, compared 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 many 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 kinds of items made out of Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and 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 subjected to weathering or UV-radiation, a special surface treatment is needed. This 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 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 and become a very thick liquid. The melted liquid polycarbonate is then rapidly injected into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
