Covestro Makrolon Polycarbonate Sheets offering light weight and break resistance
Bayer Makrolon Polycarbonate materials give you a balance of useful features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a tough material. Although it has very high impact-resistance, it possesses minimal scratch-resistance and thus a hard coating is applied to polycarbonate eye wear lenses as well as polycarbonate exterior vehicle equipment. The characteristics of polycarbonate are similar those of common Acrylic materials, except 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 it has better light transmission characteristics than several types of glass.
Polycarbonate carries a glass transition temperature of approximately 150 °C (302 °F), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools need to be held at warm to high temperatures, generally above 80 °C (176 °F) to produce strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic deformations without cracking. Subsequently, it is sometimes processed and formed cold using sheet metal techniques, which include forming bends on a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are needed, which can not be created from sheet metal. Be aware that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it is brittle and cannot be bent without heating.
The light weight of polycarbonate, compared to glass, has led to continuing development of electronic view screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and several 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 with finer detail.
Other kinds of items manufactured 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 made from 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 is needed. This either 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 begins as a solid material in the form of small pellets. In a manufacturing process called injection molding, the pelletized resin is heated until they melt. The liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
