The 42465 is a Statfree Z2 dissipative 3-layer vinyl blue Mat Top Kit designed to provide a path-to-ground and eliminate static charge generation when used as a work-surface table mat, shelf liner and cart shelf liner. The surface resistance (1x10⁶ to <1x10⁹Ω Rtt) of the top layer meets ANSI/ESD S20.20 work-surface required limit and recommendation of ANSI/ESD S4.1 for contact with ESD susceptible items. The conductive (<1x10⁹Ω Rtt) cushioned bottom layer provides additional energy absorption for components susceptible to physical shock.
