Sheffield Plastics Polycarbonate Sheets offering light weight and break resistance
Bayer Makrolon Polycarbonate materials give you a unique balance of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is a very long-lasting material. Whilst it offers considerable impact-resistance, it has got reduced scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear as well as polycarbonate exterior auto equipment. The properties relating to polycarbonate tend to be similar to that of those of common Acrylic materials, yet , polycarbonate is undoubtedly 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 several types of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic deformations without cracking. Subsequently, for small changes in shape, it can be processed and formed without needing to be heated using sheet metal techniques, such as forming bends on a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are necessary, which can't be made from sheet metal. Be aware that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but it's brittle and can't be bent at room temperature.
The light weight of polycarbonate, compared with glass, has led to advancement of electronic view screens that replace the traditional 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 the ability to be etched with finer detail.
Other kinds of items manufactured 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 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 maybe 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 plastic material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is heated until they melt. The liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to produce a finished product in less than a minute.
