Makrolon Polycarbonate products give you a unique 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 rugged material. Even though it has outstanding impact-resistance, it's got reduced scratch-resistance and thus a hard coating is applied to polycarbonate eye wear lenses as well as polycarbonate exterior vehicle components. The characteristics of polycarbonate tend to be along the lines of those of common Acrylic materials, yet , 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 has better light transmission characteristics than many kinds 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 higher temperatures, generally above 80 °C (176 °F) to make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo large deformations without breaking or cracking. Because of that, for small changes in shape, it can be processed and formed without needing to be heated using standard sheet metal techniques, which include forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are necessary, which should not be created from sheet metal. Understand 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, compared with glass, has led to continuing 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 as well as 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 in finer detail.
Other kinds of items fabricated from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, 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 is 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 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 melt in to a thick liquid. This liquid polycarbonate is then rapidly injected into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to create a finished product , all in just a minute or so.
