A laminated microporous article consisting of at least two layers or plies, the first comprising either a thermoset or thermoplastic microporous material and the second comprising a polyester non-woven, heat bonded (in distinction to adhesive bonded) web. The resulting laminated microporous article is especially useful as a battery separator and exhibits superior properties including improved electrical resistance, toughness and tear strength, and flexibility.
