Lexan Polycarbonate Sheet offering light weight and break resistance

Makrolon Polycarbonate products offer a unique balance of beneficial features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is definitely a sturdy material. Even though it has significant impact-resistance, it's got low scratch-resistance and thus a hard coating is often applied to polycarbonate eyewear as well as polycarbonate exterior auto equipment. The properties relating to polycarbonate are similar those of Acrylic PMMA materials, except 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 it has better light transmission characteristics than many kinds of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. Therefore, it can be processed and formed   cold using standard sheet metal techniques, which include forming bends with a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are crucial, which should not be created from sheet metal. Keep in mind that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and cannot be bent with out a heating process.

The light weight of polycarbonate, compared to glass, has led to development of electronic display screens that replace glass materials 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 do require glass for its higher melting temperature and the ability to be etched with finer detail.
Other types of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and blender jars. Many toys and hobby products are constructed 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 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 and become a very thick liquid. The liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
