Covestro Makrolon Polycarbonate Sheets are considered unbreakable
Polycarbonate products have a balance of helpful features including temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is a very sturdy material. Even though it features significant impact-resistance, it has got minimal scratch-resistance and thus a hard coating can be applied to polycarbonate eyeglasses lenses and polycarbonate exterior motor vehicle equipment. The characteristics relating to polycarbonate tend to be along the lines of those of polymethyl methacrylate (PMMA, acrylic), 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 about 150 °C (302 °F), so it softens slowly 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 reduced stress products.
Unlike most other thermoplastics, polycarbonate can undergo massive deformations without cracking or breaking. Because of this, for small changes in shape, it can be processed and formed cold using standard sheet metal techniques, such as forming bends on a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are essential, which should not be crafted from sheet metal. Be aware that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and can't be bent with out a heating process.
The light weight of polycarbonate, compared with glass, has led to continuing development of electronic display screens that replace the traditional 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 generally still require glass for its higher melting temperature and its ability to be etched with finer detail.
Other kinds of items made out of 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 of 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 a coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that at the beginning, starts 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 in to a thick liquid. The melted liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
