Abstract
A chemically protective laminate comprising a thin thermoplastic barrier layer, having a consistent thickness, laminated between two porous polymeric membrane layers. The porous polymeric membrane may be of porous polytetrafluoroethylene, preferably expanded porous polytetrafluoroethylene. The chemically protective laminate may be subsequently adhered to a backing to form a fabric laminate capable of being assembled into a chemically protective article.
