Glass-reinforced polycarbonate is used in many industrial applications where metals, particularly die-cast aluminum and zinc, are commonly used. The addition of glass fibers to polycarbonate in various amounts (10%, 20%, 30% and 40%) increases tensile strength, stiffness, compressive strength, and lower the thermal expansion coefficient. The greater the amount of glass fiber added to the polycarbonate, the greater the effect on each property will be.
The coefficient of thermal expansion is reduced by nearly 75%, thus equaling that of some metals. While glass-reinforced has less impact strength than standard grades, it is still tougher and more impact resistant than most other plastics and die-cast aluminum. Custom cuts and cut-to-size available.
