Makrolon Polycarbonate materials give you a great blend of beneficial features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a sturdy material. Even though it features higher impact-resistance, it has got low scratch-resistance and so a hard coating is applied to polycarbonate eye protection as well as polycarbonate exterior automobile equipment. The properties relating to polycarbonate are generally comparable to those of polymethyl methacrylate (PMMA, acrylic), 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 several types of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at higher temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo large changes in basic shape without cracking. Because of this, for small changes in shape, it can be processed and formed without needing to be heated using sheet metal techniques, such as forming bends on a brake. For even 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 required, which can't be crafted from sheet metal. Note that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it's brittle and can't be bent at room temperature.
The light weight of polycarbonate, unlike glass, has led to advancement of electronic display screens that replace glass materials 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 which still do require glass for its higher melting temperature and its ability to be etched with finer detail.
Other miscellaneous items created 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 goods 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 maybe needed. This either can be a coating (e.g. for improved abrasion resistance), or a 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 pelletized resin is heated until they begin to melt. The liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to create a finished product , all in just a minute or so.
