Lexan Polycarbonate Flat Sheet offer high impact strength

Makrolon Polycarbonate products give you a great blend of beneficial features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is a very high quality material. Though it has considerable impact-resistance, it's got reduced scratch-resistance and so a hard coating typically is applied to polycarbonate eyewear lenses as well as polycarbonate exterior auto components. The characteristics relating to polycarbonate are comparable to those of Acrylic PMMA materials, although 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 several types of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at warm to high temperatures, generally above 80 °C (176 °F) to make strain- and stress-free products.
Unlike most other thermoplastics, polycarbonate can undergo large shape changes without breaking. Because of this, it can be processed and formed   without needing to be heated using standard sheet metal techniques, such as forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which can not be crafted from sheet metal. Note that PMMA/Plexiglas, which is similar in looks to polycarbonate, but is brittle and cannot be bent unless it is heated.

The light weight of polycarbonate, unlike glass, has led to advancement of electronic view screens that replace glass materials with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink as well as LCD screens, though CRT, plasma screen and other LCD technologies which still require glass for its higher melting temperature and the ability to be etched in 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 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 maybe needed. This may be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
The 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, these small pellets are heated until they begin to melt. The melted liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to create a finished product , that only takes about a minute to complete.
