Lexan Polycarbonate Sheet offer high impact strength

Polycarbonate products offer a unique balance of helpful features including high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a durable material. Though it has extraordinary impact-resistance, it's got low scratch-resistance and thus a hard coating typically is applied to polycarbonate eye wear lenses and polycarbonate exterior automobile equipment. The characteristics associated with polycarbonate are generally comparable to those of polymethyl methacrylate (PMMA, acrylic), but 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 has better light transmission characteristics than many kinds of glass.
Polycarbonate carries 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 must be held at warm to high temperatures, generally above 80 °C (176 °F) to make strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive shape changes without breaking. As a result, for small changes in shape, it can be processed and formed   at room temperature using standard sheet metal techniques, such as forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are necessary, which can not be produced from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but it is brittle and can't be bent with out a heating process.

The light weight of polycarbonate, as opposed 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 the ability to be etched with finer detail.
Other kinds of items fabricated from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby products 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 is needed. This can be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
The 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 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 produce a finished product , that only takes about a minute to complete.
