Bayer Makrolon Polycarbonate materials have a unique balance of beneficial features this includes high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is definitely a rugged material. Even though it has outstanding impact-resistance, it possesses low scratch-resistance and so a hard coating is applied to polycarbonate eye wear as well as polycarbonate exterior vehicle equipment. The characteristics of polycarbonate are along the lines of those of common Acrylic materials, and yet polycarbonate is actually 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 near 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools should be held at high temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo large deformations without cracking or breaking. Therefore, it could be processed and formed without needing to be heated using standard sheet metal techniques, which include forming bends on a brake. Even for sharp angle bends with a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are required, which can not be produced from sheet metal. Please keep in mind PMMA/Plexiglas, that is similar in appearance to polycarbonate, but it's brittle and can't be bent without heating.
The light weight of polycarbonate, unlike glass, has led to growth and development of electronic view screens that replace glass materials 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 its ability to be etched in finer detail.
Other miscellaneous items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and blender jars. Many toys and hobby items are made 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 maybe needed. This may be a coating (e.g. for improved abrasion resistance), or a 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 melted liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to produce a finished product , that only takes about a minute to complete.
