Sheffield Plastics Polycarbonate Sheeting are clear and tough
Makrolon Polycarbonate materials give you a balance of useful features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering materials.
Polycarbonate is definitely a tough material. Although it features considerable impact-resistance, it has got minimal scratch-resistance and so a hard coating can be applied to polycarbonate eye protection lenses as well as polycarbonate exterior automobile equipment. The characteristics associated with polycarbonate are similar to those of polymethyl methacrylate (PMMA, acrylic), 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 most grades of glass.
Polycarbonate has a glass transition temperature near 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 high temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. As a result, it could be processed and formed at room temperature using sheet metal techniques, which include forming bends on a brake. Even for sharp angle bends having 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 should not be crafted from sheet metal. Understand that PMMA/Plexiglas, which happens to be similar in appearance to polycarbonate, but is brittle and cannot be bent at room temperature.
The light weight of polycarbonate, in contrast to glass, has led to continuing development of electronic display screens that replace glass materials 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 its ability to be etched with finer detail.
Other types of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and common style blender jars. Many toys and hobby goods are produced 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 is needed. This may be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
Bayer 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, this pellet material is heated until they melt and become a very thick liquid. The liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
