The TM30600L3BL is a blue Table Mat with 3-layer construction. The top layer is made from a tough, easy-to-clean dissipative vinyl. The centre layer, a highly conductive metal scrim, moves the charge from the surface to ground quickly. The bottom layer is a durable, non-skid, cushion of dissipative foam. It is compatible with constant monitors. This three-layer vinyl material provides excellent electrical properties.
