Antistatic Grades–
ESD-PTFE offers an excellent combination of low frictional properties and dimensional stability. It is ideal for applications where controlled bleed off of static charges is critical. It is black in color.
ESD-PC Sheet is a plastic sheet product that controls static electricity for many applications, including windows, doors, mini-environment glazing panels, and machine guards, covers and enclosures. This controls particulate attraction and prevents electrostatic discharge (ESD) events completely independent of humidity. It has superior impact resistance and flame-spread properties, plus excellent clarity, chemical resistance, and mar resistance.
