Unfilled Polycarbonate is a tough, transparent engineering thermoplastic which offers very high impact strength and high modulus of elasticity. It also has a high heat deflection temperature and absorbs very little moisture. These properties, plus good low frequency and high voltage insulating characteristics, make polycarbonate a prime material for electrical and electronic components. Its strength, impact resistance and transparency (unfilled grades only) also make it an ideal material for certain transparent structural applications.


Glass fibers may be added in various amounts (10%, 20%, 30% and 40%) to increase tensile strength, stiffness, compressive strength, and lower the thermal expansion coefficient. NOTE: Glass-filled polycarbonate is almost always black in color.
