Lexan Polycarbonate Flat Sheet offer high impact strength

Polycarbonate plastic materials offer a unique balance of beneficial features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a durable material. Although it has high impact-resistance, it has got minimal scratch-resistance and so a hard coating can be applied to polycarbonate eye wear and polycarbonate exterior automobile components. The properties of polycarbonate are similar those of common Acrylic materials, yet , 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 most grades of glass.
Polycarbonate has 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) to produce strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo dramatic changes in basic shape without breaking. Due to this fact, it can be processed and formed   cold using standard sheet metal techniques, such as forming bends on a brake. For even sharp angle bends having 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 should not be created from sheet metal. Be aware that PMMA/Plexiglas, which is similar in looks to polycarbonate, but is brittle and cannot be bent without heating.

The light weight of polycarbonate, compared to glass, has led to continuing development of electronic display screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and some LCD screens, though CRT, plasma screen and other LCD technologies generally still require glass for its higher melting temperature and the ability to be etched with finer detail.
Other types of items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police 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 subjected to weathering or UV-radiation, a special surface treatment maybe needed. This can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that starts as a solid material in the form of small pellets. In a manufacturing process called injection molding, the pellets are heated until they melt and become a very thick liquid. The melted liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
