Covestro Makrolon Polycarbonate Flat Sheet offering light weight and break resistance
Polycarbonate plastic products offer a great blend of beneficial features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering materials.
Polycarbonate is definitely a long-lasting material. Even though it offers outstanding impact-resistance, it's got minimal scratch-resistance and so a hard coating can be applied to polycarbonate eye protection as well as polycarbonate exterior vehicle equipment. The characteristics associated with polycarbonate are similar those of common Acrylic materials, although 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 of about 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at warm to high temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo massive deformations without cracking or breaking. As a result, it is sometimes processed and formed at room temperature using sheet metal techniques, such as forming bends with a brake. Even for 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 needed, which may not be produced from sheet metal. Remember that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and cannot be bent without heating.
The light weight of polycarbonate, compared with glass, has led to advancement of electronic view 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 kinds of items manufactured 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 products 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 could be needed. This either can be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that begins as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, the pelletized resin is heated until they melt and become a very thick liquid. This liquid polycarbonate is then rapidly pushed 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 , that only takes about a minute to complete.
