3M Dissipative Vinyl Three-Layer Mats
and Rolls (Premium Performance)
3M Mats and Rolls 8200 Series are soft table and floor mats with a
unique three-layer construction. The top layer is durable static dissipative
vinyl, which has sufficiently low resistance to discharge static-laden
conductors, yet will prevent the shorting of pins on the backs of printed
circuit boards laid on the mat. The middle layer is a highly conductive
scrim that provides the main discharge path to ground, and the bottom
layer is static dissipative foam, providing a durable nonskid cushion.
Non-standard sizes are available on a custom order basis. Compatible
with constant monitors.
