Makrolon Polycarbonate products give you a balance of helpful features which include temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastics.
Polycarbonate is a very tough material. Whilst it features high impact-resistance, it has low scratch-resistance and so a hard coating could be applied to polycarbonate eye protection lenses as well as polycarbonate exterior automotive components. The characteristics of polycarbonate are comparable to those of Acrylic PMMA materials, except 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 of around 150 °C (302 °F), as a result it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo dramatic changes in basic shape without breaking or cracking. Because of this, it could be processed and formed without needing to be heated using sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are needed, which can not be created from sheet metal. Understand that PMMA/Plexiglas, that is similar in looks to polycarbonate, but it's brittle and can't be bent unless it is heated.
The light weight of polycarbonate, in contrast to glass, has led to continuing development of electronic touch screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and some LCD screens, though CRT, plasma screen and other LCD technologies still generally require glass for its higher melting temperature and its ability to be etched with finer detail.
Other kinds of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby goods are produced 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 could be 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, these small pellets are heated until they begin to melt. The melted liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to form a finished product in less than a minute.
