Polycarbonate and Glass-filled Polycarbonate are thermoplastic polymers. They are easily worked, molded, and thermoformed, and so have a wide variety of uses. Some trade names for polycarbonate materials are HYDEX®, Hygard®, Hyzod®, Lexan®, Lexgard®, Makrofol®, Margard®, Sustanat, TECANAT®, TUFFAK® and Zelux®.
