An electrostatic mat, wherein the mat comprises at least one electrostatic layer, wherein the at least one layer comprises an elastomeric rubber, wherein the elastomeric rubber comprises 20-100 phr elastomeric polyether, wherein the elastomeric polyether comprises 10-75 wt % ethylene oxide, 20-70 wt % epihalohydrin, and 0-10% vinyloxirane.

Each cover extends at least partially across the top face of one of the mats without extending over any of the edges thereof and is flexibly coupled to the mat sufficient to allow the mat to flex, expand and contract relative to the cover due to environmental factors and the movement of personnel, vehicles and/or equipment across the load-supporting surface during normal, typical or expected use conditions.

The Nuisance Current Blocker (NCB) is a unique protective device that utilizes resistors, gas discharge tube arrestors and choke/inductors to block low level current on equipment grounding conductors while maintaining an effective ground fault path to quickly activate overcurrent protective devices. EPRI reported that 60% of the electric grid's primary return current travels back through the earth. The NEC addresses this “Objectionable Current” in Section 250.6 and provides options to remediate in (B)(3) with “Interrupt the continuity of the conductor . . . ” or (B)(4) “Take other suitable remedial and approved action” and also in 250.6(E). Residential grounding systems have no protection against primary return current. The NCB blocks this ground current from entering the home via well pumps, also reduces ground loops, magnetic fields, chokes high frequencies, and reduces contact current exposures on grounding mats, sheets, and RF shielding paint to prevent, according to the EPRI, potential cancer causing environments.

A layer of the mixture that contains polymer and conductive particles is applied over a first surface, when the mixture has a first viscosity that allows the conductive particles to rearrange within the layer. An electric field is applied over the layer, so that a number of the conductive particles are aligned with the field and thereafter the viscosity of the layer is changed to a second, higher viscosity, in order to mechanically stabilise the layer. This leads to a stable layer with enhanced and anisotropic conductivity.
