PC (technical quality) – Polycarbonate (technical grade)


PC GF30 is a technical polycarbonate with added glass. The additive gives the material good mechanical tensile strength, wear resistance and dimensional accuracy. The material has extremely low absorption of water. We deliver PC GF30 as plastic sheets and rods.
