Lexan Polycarbonate Flat Sheet are clear and tough
Polycarbonate products offer a great blend of beneficial features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a high quality material. Whilst it features outstanding impact-resistance, it has got lower scratch-resistance and thus a hard coating can be applied to polycarbonate eyewear and polycarbonate exterior automotive components. The characteristics relating to polycarbonate are generally like those of Acrylic PMMA 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 has better light transmission characteristics than most grades of glass.
Polycarbonate has 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) to help make strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic deformations without breaking. For this reason, it can be processed and formed without needing to be heated using standard sheet metal techniques, for example forming bends with a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are required, which can not be crafted from sheet metal. Remember that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it's brittle and can't be bent without heating.
The light weight of polycarbonate, as opposed to glass, has led to 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 several 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 miscellaneous 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 items 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 can be a coating (e.g. for improved abrasion resistance), or perhaps the 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, these small pellets are heated until they melt in to a thick liquid. This 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 form a finished product , all in just a minute or so.
