Lexan Polycarbonate Sheets offering light weight and break resistance

Bayer Makrolon Polycarbonate products give you a balance of useful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a high quality material. Even though it offers significant impact-resistance, it has reduced scratch-resistance and so a hard coating is applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior motor vehicle components. The properties of polycarbonate are generally similar to that of those of Acrylic PMMA materials, 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 many kinds of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at warm to high temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo massive shape changes without breaking. For this reason, it is sometimes processed and formed   without needing to be heated using sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are essential, which cannot be made from sheet metal. Note that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and can't be bent with out a heating process.

The light weight of polycarbonate, as opposed to 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 and a few LCD screens, though CRT, plasma screen and other LCD technologies still generally require glass for its higher melting temperature and the ability to be etched in finer detail.
Other types of items created from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and common style blender jars. Many toys and hobby items 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 either 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 begins as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, the pelletized resin is heated until they melt in to a thick liquid. The liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to form a finished product , all in just a minute or so.
