Sheffield Plastics Polycarbonate Sheet offer high impact strength
Bayer Makrolon Polycarbonate materials give you a balance of helpful features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is definitely a high quality material. Whilst it offers increased impact-resistance, it possesses lower scratch-resistance and so a hard coating may be applied to polycarbonate eye protection lenses as well as polycarbonate exterior auto equipment. The properties of polycarbonate tend to be similar to those of polymethyl methacrylate (PMMA, acrylic), 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 has a glass transition temperature near 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at high temperatures, generally above 80 °C (176 °F) in order to make strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large deformations without cracking. Due to this fact, for small changes in shape, it can be processed and formed without needing to be heated using sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are necessary, which may not be crafted from sheet metal. Be aware that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but is brittle and can't be bent without heating.
The light weight of polycarbonate, in contrast to glass, has led to advancement of electronic view screens that replace glass materials with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and some 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 in finer detail.
Other kinds of items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby goods 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 is needed. This either can be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that 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 begin to melt. The melted liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
