Covestro Makrolon Polycarbonate Flat Sheet are clear and tough
Makrolon Polycarbonate products have a great blend of useful features which include high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials.
Polycarbonate is a very high quality material. Though it features exceptional impact-resistance, it's got lower scratch-resistance and thus a hard coating can be applied to polycarbonate eye wear lenses as well as polycarbonate exterior auto equipment. The properties relating to polycarbonate tend to be similar those of Acrylic PMMA materials, and yet polycarbonate is definitely 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 gradually above this point and flows above about 300°C (572 °F). Tools must be held at high temperatures, generally above 80 °C (176 °F) to make strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo massive deformations without cracking or breaking. Subsequently, it can be processed and formed cold using sheet metal techniques, for instance forming bends on a brake. Even for 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 needed, which should not be produced from sheet metal. Please keep in mind PMMA/Plexiglas, that 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 glass materials 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 in finer detail.
Other miscellaneous 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 manufactured 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 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 pellets are heated until they begin to melt. The liquid polycarbonate is then rapidly pushed into a mold, compressed under high pressure and cooled to produce a finished product in a matter of minutes.
