Polyethylene Foam Compounded for Permanent ESD Control Properties. Creates ESD properties that will not degrade. Superior to pink dissipative products where <10E9 Rtt and cushioning is required, such as worksurfaces, shelving, cart shelves, or material handling containers. The foam will electrically couple to a grounded ESD worksurface when placed on the worksurface; no need for a separate ground cord.
