Lexan Polycarbonate Sheet are considered unbreakable
Makrolon Polycarbonate materials have a balance of useful features this includes temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a long-lasting material. Although it offers very high impact-resistance, it has got a lower scratch-resistance and thus a hard coating could be applied to polycarbonate eyewear as well as polycarbonate exterior auto equipment. The characteristics associated with polycarbonate tend to be similar to those of Acrylic PMMA materials, and yet 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 carries a glass transition temperature of around 150 °C (302 °F), therefore it softens gradually above this point and flows above about 300°C (572 °F). Tools are required to be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and stress-free products.
Unlike most thermoplastics, polycarbonate can undergo large changes in basic shape without breaking. Because of this, for small changes in shape, it can be processed and formed without needing to be heated using sheet metal techniques, for example forming bends with a brake. For even 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 needed, which cannot be crafted from sheet metal. Please keep in mind PMMA/Plexiglas, which happens to be similar in looks to polycarbonate, but is brittle and can't be bent with out a heating process.
The light weight of polycarbonate, as opposed to glass, has led to advancement of electronic view screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and a few 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 manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, high impact riot shields, instrument panels, and common style blender jars. Many toys and hobby products are produced from 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 perhaps the coextrusion for enhanced weathering resistance.
Bayer Makrolon Polycarbonate is a thermoplastic that starts 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 in to a thick liquid. This liquid polycarbonate is then rapidly injected into the mold - shaped like the part, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
