Lexan Polycarbonate Flat Sheet offering light weight and break resistance
Polycarbonate plastic materials give you a balance of beneficial features including high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastics and engineering plastic materials.
Polycarbonate is definitely a sturdy material. Whilst it features greater impact-resistance, it has got low scratch-resistance and so a hard coating typically is applied to polycarbonate eyeglasses as well as polycarbonate exterior motor vehicle components. The properties relating to polycarbonate are generally similar those of Acrylic PMMA materials, but polycarbonate is undoubtedly 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 several types of glass.
Polycarbonate has a glass transition temperature of around 150 °C (302 °F), therefore it softens slowly above this point and flows above about 300°C (572 °F). Tools are required to be held at higher temperatures, generally above 80 °C (176 °F) to help with making strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking or cracking. Subsequently, it is sometimes processed and formed at room temperature using sheet metal techniques, for instance forming bends on a brake. Even for 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 essential, which can't be made from sheet metal. Understand that PMMA/Plexiglas, that is certainly similar in appearance to polycarbonate, but it's brittle and cannot be bent at room temperature.
The light weight of polycarbonate, as opposed to glass, has led to continuing 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 some 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 with finer detail.
Other miscellaneous items made out of 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 items are constructed 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 is needed. This either 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 at the beginning, starts as a solid plastic material in the form of small pellets. In a manufacturing process called injection molding, the pellets are heated until they melt. The liquid polycarbonate is then rapidly pushed 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.
