Sheffield Plastics Polycarbonate Sheeting offer high impact strength
Makrolon Polycarbonate products have a unique balance of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is definitely a long-lasting material. Whilst it offers tremendous impact-resistance, it possesses lower scratch-resistance and thus a hard coating may be applied to polycarbonate eye wear lenses as well as polycarbonate exterior auto equipment. The characteristics relating to polycarbonate are generally 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 several types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) to produce strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo massive deformations without cracking or breaking. Because of this, it can be processed and formed at room temperature using sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which may not be produced from sheet metal. Understand that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but is brittle and cannot be bent without heating.
The light weight of polycarbonate, as opposed to glass, has led to growth and development of electronic display screens that replace glass 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 generally still require glass for its higher melting temperature and the ability to be etched in finer detail.
Other kinds of items produced from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact 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 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 produce a finished product in less than a minute.
