Sheffield Plastics Polycarbonate Sheeting offering light weight and break resistance
Makrolon Polycarbonate products have a balance of helpful features including temperature resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a sturdy material. Whilst it features increased impact-resistance, it has got lower scratch-resistance and thus a hard coating typically is applied to polycarbonate eyeglasses and polycarbonate exterior vehicle equipment. The characteristics relating to polycarbonate are generally similar to that of those of common Acrylic materials, and yet polycarbonate definitely is 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 around 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 higher temperatures, generally above 80 °C (176 °F) to produce strain- and reduced stress products.
Unlike many thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking or cracking. Subsequently, for small changes in shape, it can be processed and formed at room temperature using sheet metal techniques, which include forming bends with 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 should not be created from sheet metal. Keep in mind that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and cannot be bent with out a heating process.
The light weight of polycarbonate, compared to glass, has led to continuing development of electronic touch screens that replace the traditional glass 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 its ability to be etched with finer detail.
Other miscellaneous items produced from 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 products 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 either 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 at the beginning, starts as a solid material in the form of small pellets. In a manufacturing process called injection molding, the pelletized resin is heated until they melt in to a thick liquid. 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 create a finished product in less than a minute.
