Anti-static polycarbonate, also known as electrostatic dissipative (ESD) polycarbonate, is a polycarbonate sheet coated with metal and plastic mixture that prevents static electricity from being generated on the plastic sheets. Anti-static ESD polycarbonate's coating is permanent and therefore is not affected by humidity as temporary topical anti-static coatings. In addition to its anti-static properties, it has superior impact and chemical resistance.
