Covestro Makrolon Polycarbonate Flat Sheet offer high impact strength
Makrolon Polycarbonate products offer a unique balance of helpful features this includes temp resistance, impact resistance and optical properties position polycarbonates between commodity plastics and engineering plastics.
Polycarbonate is a very long-lasting material. Though it offers extraordinary impact-resistance, it possesses a lower scratch-resistance and thus a hard coating is applied to polycarbonate eyeglasses as well as polycarbonate exterior automotive equipment. The characteristics relating to polycarbonate are generally similar those of Acrylic PMMA materials, except polycarbonate definitely is 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), as a result it softens gradually above this point and flows above about 300°C (572 °F). Tools must be held at warm to high temperatures, generally above 80 °C (176 °F) to help with making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic changes in basic shape without breaking. For this reason, it is sometimes processed and formed at room temperature using standard sheet metal techniques, such as forming bends with a brake. For even sharp angle bends having a tight radius, no heating is usually necessary. This makes it attractive prototyping applications where transparent or electrically non-conductive parts are crucial, which cannot be crafted from sheet metal. Understand that PMMA/Plexiglas, which is similar in appearance to polycarbonate, but it's brittle and can't be bent unless it is heated.
The light weight of polycarbonate, compared to glass, has led to growth and development of electronic touch screens that replace the traditional glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and many LCD screens, though CRT, plasma screen and other LCD technologies which still require glass for its higher melting temperature and the ability to be etched with finer detail.
Other miscellaneous items made 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 goods are manufactured 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 maybe needed. This may be a coating (e.g. for improved abrasion resistance), or as a 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 melt. The melted liquid polycarbonate is then rapidly pushed into a mold with the empty part being the size and shape of the part you want, compressed under high pressure and cooled to form a finished product in less than a minute.
