1. A flame retardant, electromagnetic interference (EMI) shielding gasket comprising:

  • a resilient core member extending lengthwise along a central longitudinal axis and having an outer surface extending circumferentially about said longitudinal axis, said core member being formed of a foamed elastomeric material;

    an electrically-conductive fabric member surrounding the outer surface of said core member, said fabric member having an interior surface disposed facing the outer surface of said core member and an oppositely-facing, exterior surface, at least the exterior surface being electrically-conductive and the exterior surface defining with the interior surface a thickness dimension of the fabric member therebetween; and

    a flame retardant layer coating at least a portion of the interior surface of said fabric member, said flame retardant layer comprising at least about 50% by dry weight of one or more flame retardant additives and penetrating into said fabric member to a depth which is less than the thickness dimension of said fabric member such that the exterior surface of said fabric member remains electrically-conductive.
