Lexan Polycarbonate Sheeting offer high impact strength

Polycarbonate plastic products offer a great blend of beneficial features including temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is a very tough material. Whilst it offers very high impact-resistance, it has got minimal scratch-resistance and so a hard coating typically is applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior auto equipment. The characteristics of polycarbonate are comparable to those of polymethyl methacrylate (PMMA, acrylic), but 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 it has better light transmission characteristics than many kinds of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools need to be held at higher temperatures, generally above 80 °C (176 °F) in order to make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo large deformations without cracking. Because of this, it may be processed and formed   cold using standard sheet metal techniques, such as forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are required, which cannot be created from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and can't be bent without heating.

The light weight of polycarbonate, compared with glass, has led to continuing 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 several LCD screens, though CRT, plasma screen and other LCD technologies still generally require glass for its higher melting temperature and its ability to be etched in finer detail.
Other kinds of items created from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact 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 exposed to weathering or UV-radiation, a special surface treatment could be needed. This can be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
Bayer 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, this pellet material is heated until they melt and become a very thick liquid. The liquid polycarbonate is then rapidly pushed into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to create a finished product in a matter of minutes.
