Sheffield Plastics Polycarbonate Sheets are clear and tough
Bayer Makrolon Polycarbonate materials give you a balance of helpful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very long-lasting material. Whilst it offers tremendous impact-resistance, it has reduced scratch-resistance and thus a hard coating can be applied to polycarbonate eye wear lenses as well as polycarbonate exterior auto components. The characteristics associated with polycarbonate are along the lines of those of common Acrylic materials, and yet polycarbonate is definitely 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 most grades of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large deformations without breaking or cracking. For that reason, it could be processed and formed without needing to be heated using standard sheet metal techniques, such as forming bends on 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 necessary, which can not be made from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and cannot be bent at room temperature.
The light weight of polycarbonate, as opposed to glass, has led to advancement 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 which still require glass for its higher melting temperature and its ability to be etched in finer detail.
Other kinds of items fabricated from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby products 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 either can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
Bayer 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 pellets are heated until they melt and become a very thick liquid. The liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to form a finished product , all in just a minute or so.
