Makrolon Polycarbonate materials give you a balance of beneficial features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is a very sturdy material. Whilst it offers considerable impact-resistance, it's got reduced scratch-resistance and so a hard coating typically is applied to polycarbonate eye protection lenses as well as polycarbonate exterior vehicle equipment. The properties relating to polycarbonate are generally like those of Acrylic PMMA materials, yet , polycarbonate is going to be 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 many different types of glass.
Polycarbonate has 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 ought to be held at warm to high temperatures, generally above 80 °C (176 °F) to make strain- and stress-free products.
Unlike many thermoplastics, polycarbonate can undergo dramatic deformations without cracking or breaking. Subsequently, it could be processed and formed at room temperature 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 attractive prototyping applications where transparent or electrically non-conductive parts are important, which cannot be produced from sheet metal. Be aware that PMMA/Plexiglas, that is similar in looks to polycarbonate, but is brittle and cannot be bent without heating.
The light weight of polycarbonate, compared to glass, has led to development of electronic touch screens that replace the traditional glass 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 still generally require glass for its higher melting temperature and the ability to be etched in finer detail.
Other types of items made out of Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and blender jars. Many toys and hobby products are constructed 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 can be a coating (e.g. for improved abrasion resistance), or perhaps the coextrusion for enhanced weathering resistance.
Bayer 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 pellets are heated until they melt. The melted liquid polycarbonate is then rapidly injected into molds, compressed under high pressure and cooled to produce a finished product , all in just a minute or so.
