Bayer Makrolon Polycarbonate materials have a unique balance of helpful features which include temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very long-lasting material. Even though it features considerable impact-resistance, it's got reduced scratch-resistance and so a hard coating may be applied to polycarbonate eye protection as well as polycarbonate exterior automobile equipment. The characteristics of polycarbonate tend to be similar to those of Acrylic PMMA materials, except polycarbonate is definitely 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 has a glass transition temperature of approximately 150 °C (302 °F), as a result 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 make strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo large deformations without breaking. Hence, it is sometimes processed and formed cold using standard sheet metal techniques, such as forming bends on a brake. Even for 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 important, which should not be produced from sheet metal. Note that PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and cannot be bent at room temperature.
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 and many 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 in finer detail.
Other kinds of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and common style blender jars. Many toys and hobby products are made 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 can be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that at the beginning, starts 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 the mold - shaped like the part, compressed under high pressure and cooled to produce a finished product in less than a minute.
