Durable rubber material table mat, dissipative 3-layer vinyl construction. Z2 material is a highly effective 3-layer material. Its durable Statfree vinyl top layer makes it suited for use as an ESD protective bench mat. Its highly conductive middle layer provides a faster discharge path to ground. The cushioned dissipative bottom layer provides excellent protection against physical damage, and makes it easier to pick up small parts. The heat fused vinyl composite resists delamination, and is compatible for use with continuous monitors. Desco's Statfree Z2 mat is a 0.125 Inch thick, 3-layer, dissipative heat fused vinyl composite material. It is designed to provide a path-to-ground and eliminate static charge generation when used as a worksurface table mat, shelf liner, and cart shelf liner. The surface resistance (1 x 10^6 - < 1 x 10^9 ohm RTT) of the top layer meets ANSI/ESD S20.20 worksurface required limit and recommendation of ANSI/ESD S4.1 for contact with ESD susceptible items. The conductive (< 10^4 ohm RTT) middle layer reduces the resistance to ground (RTG) from the surface layer of the mat to the groundable point ground and allows the mats to be used with ESD workstation continuous monitors. The dissipative (1 x 10^6 - < 1 x 10^9 ohm RTT) cushioned bottom layer provides additional energy absorption for components susceptible to physical shock.
