Abstract:
A flame retardant, electromagnetic interference (EMI) shielding gasket comprising:a resilient core member which is not V-0 rated under Underwriter's Laboratories (UL) Standard No. 94 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 being effective to afford said gasket a flame class rating of V-0 under Underwriter's Laboratories (UL) Standard No. 94 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.
