The SCS 8905 Dissipative ESD 2-Layer Rubber Worksurface Mat Roll, Blue, 0.065 in. X 48 in. X 50 ft. provides a worksurface that does not generate a static charge and will control the discharge rate from all conductors (including ESD susceptible items) that are placed on the surface. This model also offers increased resistance to heat and hot solder as compared to vinyl or olefin materials. The product is constructed using a top color layer of static dissipative neoprene rubber laminated to a bottom black layer of conductive neoprene rubber. Both layers are made from vulcanized synthetic rubber, which offers resistance to oil, grease and most common solvents.
