Makrolon Polycarbonate products give you a unique balance of beneficial features including temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a rugged material. Whilst it features outstanding impact-resistance, it has got minimal scratch-resistance and so a hard coating may be applied to polycarbonate eye protection lenses as well as polycarbonate exterior auto components. The properties associated with polycarbonate are comparable to those of Acrylic PMMA materials, 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 has better light transmission characteristics than many different types of glass.
Polycarbonate has 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 must be held at high temperatures, generally above 80 °C (176 °F) for making strain- and almost stress free products.
Unlike many thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking. Subsequently, it could be processed and formed at room temperature using standard sheet metal techniques, which include forming bends on a brake. For even sharp angle bends with a tight radius, no heating is generally necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are necessary, which can not be created from sheet metal. Please keep in mind PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but is brittle and cannot be bent at room temperature.
The light weight of polycarbonate, compared to 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 many LCD screens, though CRT, plasma screen and other LCD technologies still generally require glass for its higher melting temperature and the ability to be etched in finer detail.
Other kinds of items made out of 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 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 perhaps the coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that begins 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. The melted 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 form a finished product , that only takes about a minute to complete.
