PC Hard

PC Hard is a coated polycarbonate. The coating considerably improves the material’s abrasion resistance without affecting its excellent optical properties. The coating is necessary in applications subject to abrasion (such as windscreen wipers) and scratching. Because of the material’s impact strength and lightness, PC Hard sheets are widely used for safety glazing in work machines. The material is also weather‑resistant, with excellent resistance to low temperatures and UV radiation. We deliver PC Hard as plastic sheets.
