Bayer Makrolon Polycarbonate Sheets are clear and tough

Makrolon Polycarbonate products have a unique balance of helpful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very sturdy material. Though it features higher impact-resistance, it has minimal scratch-resistance and so a hard coating is applied to polycarbonate eye protection and polycarbonate exterior motor vehicle equipment. The properties of polycarbonate are similar to those of common Acrylic materials, yet , polycarbonate 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 around 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to produce strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large shape changes without breaking or cracking. For this reason, for small changes in shape, it can be processed and formed   without needing to be heated using sheet metal techniques, such as forming bends with a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are necessary, which can't be crafted from sheet metal. Understand that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it's brittle and cannot be bent at room temperature.

The light weight of polycarbonate, as opposed to glass, has led to growth and 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 many 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 made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and common style 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 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 at the beginning, starts as a solid plastic 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. This liquid polycarbonate is then rapidly injected into a mold, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
