Bayer Makrolon Polycarbonate Flat Sheet are clear and tough
Makrolon Polycarbonate materials give you a balance of beneficial features this includes high temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering plastics.
Polycarbonate is definitely a long-lasting material. Whilst it has considerable impact-resistance, it has low scratch-resistance and so a hard coating is applied to polycarbonate eyeglasses lenses as well as polycarbonate exterior motor vehicle equipment. The characteristics associated with polycarbonate tend to be like those of Acrylic PMMA materials, although 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 many different types of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), so it softens slowly above this point and flows above about 300°C (572 °F). Tools need to be held at high temperatures, generally above 80 °C (176 °F) for making strain- and stress-free products.
Unlike almost all other thermoplastics, polycarbonate can undergo large deformations without breaking. Therefore, for small changes in shape, it can be processed and formed cold using sheet metal techniques, which include forming bends with a brake. Even for sharp angle bends having a tight radius, no heating is usually necessary. This makes it valuable in prototyping applications where transparent or electrically non-conductive parts are crucial, which may not be created from sheet metal. Understand that PMMA/Plexiglas, which is similar in looks to polycarbonate, but it is brittle and cannot be bent at room temperature.
The light weight of polycarbonate, compared to glass, has led to growth and development of electronic view screens that replace glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink as well as 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 miscellaneous items produced 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 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 is needed. This can 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 material in the form of small pellets. In a manufacturing process called injection molding, this pellet material is heated until they melt in to a thick liquid. This liquid polycarbonate is then rapidly pushed into the mold - shaped like the part, compressed under high pressure and cooled to create a finished product in less than a minute.
