Lexan Polycarbonate Sheet offer high impact strength
Polycarbonate materials give you a unique balance of beneficial features this includes temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastic materials.
Polycarbonate is definitely a rugged material. Though it features increased impact-resistance, it's got lower scratch-resistance and so a hard coating is often applied to polycarbonate eyewear lenses as well as polycarbonate exterior motor vehicle components. The properties associated with polycarbonate are along the lines of those of polymethyl methacrylate (PMMA, acrylic), although 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 has better light transmission characteristics than many kinds of glass.
Polycarbonate has a glass transition temperature of approximately 150 °C (302 °F), in order that it softens gradually above this point and flows above about 300°C (572 °F). Tools ought to be held at high temperatures, generally above 80 °C (176 °F) to help make strain- and reduced stress products.
Unlike almost all other thermoplastics, polycarbonate can undergo large deformations without cracking or breaking. Due to this fact, it can be processed and formed cold using standard sheet metal techniques, such as forming bends on a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it attractive 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 it's brittle and can't be bent at room temperature.
The light weight of polycarbonate, compared with glass, has led to development of electronic view screens that replace glass 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 its ability to be etched in finer detail.
Other miscellaneous items manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby items 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 is needed. This can be a coating (e.g. for improved abrasion resistance), or a 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, these small pellets are heated until they melt and become a very thick liquid. This liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to form a finished product , that only takes about a minute to complete.
