Sheffield Plastics Polycarbonate Sheets are considered unbreakable
Bayer Makrolon Polycarbonate materials give you a balance of useful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is a very rugged material. Whilst it has increased impact-resistance, it has lower scratch-resistance and thus a hard coating may be applied to polycarbonate eye protection and polycarbonate exterior automotive equipment. The properties relating to polycarbonate tend to be similar to those of common Acrylic materials, and 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 several types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools will have to be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking. Because of this, it could be processed and formed at room temperature using standard 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 crucial, which can not be made from sheet metal. Be aware that PMMA/Plexiglas, which 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 display screens that replace the traditional glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and a few 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 miscellaneous 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 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 may be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
The 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, these small 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 produce a finished product , that only takes about a minute to complete.
