Polycarbonate:           

Polycarbonate is better known by its trade name Lexan, Merlon and Polycarbafil. They are high toughness and heat resistance, high strength and rigidity, excellent creep resistance and good fatigue strength. They can be easily molded, extruded and machined. It can be nailed and riveted without cracking. They are relatively high in cost. These plastics are widely used in modern manufacturing as they can be easily worked, molded and thermoformed.

Although polycarbonate has high impact-resistance, it has low scratch-resistance. The characteristics of polycarbonate are quite like those of polymethyl methacrylate, but polycarbonate is stronger and more expensive

They are used to glass for street lamps, windows and machine guards. They retain their toughness and strength at temperature from -138 to 120°C. They are also used in power tools, household equipment and blow-molded bottles.
