P421

5-Mil PTFE Film Tape

P421 is a 6.5 mil, PTFE film tape. It is ideal for use wherever a slick surface is needed to speed up the movement of materials or reduce equipment wear. P421 is often used to prevent electrolytic corrosion of dissimilar metals, and to mask parts placed in chemical, cleaning or electroplating solutions. It is also used as an anti-vibration cushion, as a gasket for flanges, joints and clamp connectors; and as a high temperature release surface on heat sealer bars and rollers.
