The Desco 66211 Dissipative Dual Layer Rubber Mat Kit, Light Blue, .060 in. X 24 in. X 36 in., provides reliable path to ground and eliminates static charge generation as a worksurface table mat, shelf liner, and cart liner. The top layer of the mat meets the ANSI/ESD S20.20 worksurface required limit as well as the recommendation of ANSI/ESD S4.1 for contact with ESD susceptible items. The dedicated conductive bottom layer reduces the resistance to ground (Rtg) from the top of the surface to the groundable point ground and allows the mat to be used with ESD workstation monitors. The mat is heat and chemical resistant, allowing it to be used with a soldering iron, flux, and other chemicals.
