Covestro Makrolon Polycarbonate Sheets offering light weight and break resistance

Polycarbonate products offer a great blend of helpful features including temp resistance, impact resistance and optical properties position polycarbonates between commodity plastic materials and engineering materials.
Polycarbonate is definitely a rugged material. Although it features higher impact-resistance, it possesses reduced scratch-resistance and so a hard coating may be applied to polycarbonate eyewear as well as polycarbonate exterior automotive components. The characteristics relating to polycarbonate tend to be like those of Acrylic PMMA materials, but 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 has better light transmission characteristics than many different types of glass.
Polycarbonate carries a glass transition temperature of about 150 °C (302 °F), consequently it softens slowly above this point and flows above about 300°C (572 °F). Tools will have to be held at higher temperatures, generally above 80 °C (176 °F) in order to make strain- and almost stress free products.
Unlike most other thermoplastics, polycarbonate can undergo large deformations without breaking or cracking. For that reason, it can be 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 important, which can't be crafted from sheet metal. Remember that PMMA/Plexiglas, that is similar in appearance 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 touch screens that replace the traditional glass with polycarbonate, for use in mobile and portable devices. Such displays include newer e-ink and a few 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 manufactured from Polycarbonate include durable, lightweight luggage, MP3/digital audio player cases, computer cases, police riot shields, instrument panels, and blender jars. Many toys and hobby products 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 could be needed. This either can be a coating (e.g. for improved abrasion resistance), or a coextrusion for enhanced weathering resistance.
The Makrolon Polycarbonate is a thermoplastic that begins 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 liquid polycarbonate is then rapidly pushed into molds, compressed under high pressure and cooled to create a finished product , that only takes about a minute to complete.

The California Lemon Law

California’s lemon law is designed to protect consumers by requiring car companies and consumer goods manufacturers to repurchase or replace vehicles or products that suffer from warranty defects that cannot be fixed in a reasonable number - usually at least 2 - of attempts. Warranties categories include express warranty and implied warranty. Express warranties are made in writing, making specific promises about product or vehicle repair. This is the one included in an owner’s manual. An implied warranty is not in writing but happens at the time of the sale, with the manufacturer assuming the responsibility to correct any defect that might occur. For example, if you buy a car or product that is still under warranty and turns out to be a lemon you are entitled to get a partial or full refund. The California lemon law requires car companies to pay for the consumer’s attorney’s fees and costs if the customer wins a lemon lawsuit. As a result, all attorney fees are paid for by the car man...
