Sheffield Plastics Polycarbonate Sheeting offering light weight and break resistance

Bayer Makrolon Polycarbonate products have a balance of helpful features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is a very long-lasting material. Although it has significant impact-resistance, it has a lower scratch-resistance and so a hard coating can be applied to polycarbonate eye wear as well as polycarbonate exterior vehicle equipment. The characteristics of polycarbonate tend to be along the lines of those of Acrylic PMMA materials, but polycarbonate is always 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 several types of glass.
Polycarbonate has a glass transition temperature near 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools ought to be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive deformations without breaking or cracking. Hence, it may be processed and formed   without needing to be heated using sheet metal techniques, for instance forming bends with a brake. Even for 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 needed, which can not be crafted from sheet metal. Understand that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it is brittle and can't be bent with out a heating process.

The light weight of polycarbonate, in contrast to glass, has led to growth and development of electronic touch screens that replace glass materials with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and a few 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 produced 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 made out of 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 begins as a solid material in the form of small pellets. In a manufacturing process called injection molding, the pellets are heated until they begin to melt. The melted 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 create a finished product in less than a minute.
