Covestro Makrolon Polycarbonate Sheet are considered unbreakable
Polycarbonate products offer a great blend of useful features including high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a high quality material. Even though it features higher impact-resistance, it has reduced scratch-resistance and thus a hard coating may be applied to polycarbonate eye wear lenses as well as polycarbonate exterior automobile equipment. The characteristics associated with polycarbonate are similar those of polymethyl methacrylate (PMMA, acrylic), except polycarbonate is actually 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 it has better light transmission characteristics than many kinds of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), so it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike most thermoplastics, polycarbonate can undergo large shape changes without cracking or breaking. Because of this, it can be processed and formed cold using sheet metal techniques, which include forming bends with a brake. Even for 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 crucial, which may not be made from sheet metal. Remember that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it's brittle and can't be bent with out a heating process.
The light weight of polycarbonate, unlike glass, has led to 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 which still do require glass for its higher melting temperature and the ability to be etched with finer detail.
Other miscellaneous items fabricated 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 goods are made out 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 is needed. This may be a coating (e.g. for improved abrasion resistance), or 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 and become a very thick liquid. The 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 , that only takes about a minute to complete.
