Bayer Makrolon Polycarbonate Sheet offer high impact strength
Bayer Makrolon Polycarbonate materials offer a great blend of useful features which include high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very durable material. Even though it offers outstanding impact-resistance, it has reduced scratch-resistance and so a hard coating can be applied to polycarbonate eye wear lenses and polycarbonate exterior vehicle components. The properties associated with polycarbonate are generally along the lines of those of polymethyl methacrylate (PMMA, acrylic), although 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 most grades of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), in order that it softens slowly 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 reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo dramatic deformations without breaking or cracking. Subsequently, 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. Even for sharp angle bends with a tight radius, no heating is generally necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are important, which can not be created from sheet metal. Be aware that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it's brittle and can't be bent at room temperature.
The light weight of polycarbonate, in contrast to 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 generally still require glass for its higher melting temperature and the ability to be etched with finer detail.
Other types of items manufactured 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 could be needed. This can be a coating (e.g. for improved abrasion resistance), or perhaps the 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, these small pellets are heated until they melt. The melted liquid polycarbonate is then rapidly injected into a mold, compressed under high pressure and cooled to form a finished product in less than a minute.
