Polycarbonate is a unique engineering thermoplastic which has an excellent balance of clarity and toughness while displaying a wide range of high-heat deflection temperatures. Toughness is the most outstanding feature of polycarbonate; for applications such as safety shields and sports equipment this durable material is without equal. Other characteristics include excellent electrical properties, dimensional stability and inherent ignition resistant properties.

The close tolerance machinability and transparency of this material make it appropriate for applications which require high performance characteristics. This combination of physical properties make it a useful material for the automotive, industrial/business machine and appliance markets. Polycarbonate is available in both general purpose and FDA grades. General purpose polycarbonate is enhanced by the addition of thermal stabilizers, U.V. stabilizers, mold release agents, glass fibers and ignition resistant additives. Fabrication techniques such as milling, forming or cutting can be performed using standard equipment and tools. Note: See also Tuffak
