Covestro Makrolon Polycarbonate Sheet offer high impact strength
Polycarbonate products offer a balance of beneficial features this includes high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering plastics.
Polycarbonate is a very long-lasting material. Whilst it offers exceptional impact-resistance, it has lower scratch-resistance and thus a hard coating can be applied to polycarbonate eye protection lenses as well as polycarbonate exterior vehicle components. The characteristics of polycarbonate are generally like 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 kinds of glass.
Polycarbonate carries a glass transition temperature of around 150 °C (302 °F), consequently it softens gradually above this point and flows above about 300°C (572 °F). Tools should be held at warm to high temperatures, generally above 80 °C (176 °F) in order to make strain- and reduced stress products.
Unlike most thermoplastics, polycarbonate can undergo massive changes in basic shape without breaking. Because of this, it is sometimes processed and formed at room temperature using standard sheet metal techniques, for instance forming bends with a brake. For even sharp angle bends with a tight radius, no heating is usually necessary. This makes it useful for prototyping applications where transparent or electrically non-conductive parts are required, which cannot be crafted from sheet metal. Remember that PMMA/Plexiglas, that is certainly similar in looks to polycarbonate, but it is brittle and can't be bent unless it is heated.
The light weight of polycarbonate, compared to glass, has led to continuing development of electronic display 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 the ability to be etched in finer detail.
Other types of items made from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, riot shields, instrument panels, and blender jars. Many toys and hobby products are made 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 may be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
The 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 begin to melt. This 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 produce a finished product , that only takes about a minute to complete.
