Lexan Polycarbonate Sheeting offer high impact strength

Makrolon Polycarbonate products have a balance of beneficial features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is a very high quality material. Even though it has outstanding impact-resistance, it's got reduced scratch-resistance and so a hard coating could be applied to polycarbonate eye protection lenses as well as polycarbonate exterior automotive equipment. The characteristics associated with polycarbonate are similar those of common Acrylic materials, although polycarbonate definitely is 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 different types 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 should be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo large changes in basic shape without cracking or breaking. For this reason, it is sometimes processed and formed   without needing to be heated using sheet metal techniques, for example forming bends on a brake. Even for 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. Understand that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and can't be bent unless it is heated.

The light weight of polycarbonate, compared to glass, has led to continuing 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 its ability to be etched with finer detail.
Other types of items made out of 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 manufactured 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 maybe needed. This may be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that at the beginning, starts as a solid 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. This 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 , that only takes about a minute to complete.
