Bayer Makrolon Polycarbonate Sheeting offering light weight and break resistance
Makrolon Polycarbonate materials have a unique balance of useful features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a high quality material. Whilst it has increased impact-resistance, it's got low scratch-resistance and thus a hard coating may be applied to polycarbonate eyeglasses as well as polycarbonate exterior automobile equipment. The properties relating to polycarbonate are generally similar those of common Acrylic materials, and yet 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 it has better light transmission characteristics than most grades of glass.
Polycarbonate carries a glass transition temperature near 150 °C (302 °F), as a result 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 help make strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo dramatic deformations without cracking or breaking. Because of this, it can be processed and formed cold using standard sheet metal techniques, for instance forming bends on a brake. For even sharp angle bends having a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are required, which can not be created from sheet metal. Note that PMMA/Plexiglas, that is similar in appearance to polycarbonate, but is brittle and cannot be bent without heating.
The light weight of polycarbonate, in contrast to glass, has led to growth and development of electronic touch screens that replace glass materials with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and several LCD screens, though CRT, plasma screen and other LCD technologies which still do require glass for its higher melting temperature and its ability to be etched with finer detail.
Other types of items fabricated 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 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 could be needed. This may be a coating (e.g. for improved abrasion resistance), or as a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that at the beginning, starts as a solid material in the form of small pellets. In a manufacturing process called injection molding, these small pellets are heated until they melt and become a very thick liquid. 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.
