摘要:Fully cured thermoset ethylene-propylene rubber sheets having integral thermoplastic adhesive strips molded along the lateral edges are produced using a manufacturing method where the strips are applied prior to vulcanization of the rubber sheeting. The factory applied adhesive strip is non-tacky and dry but is activated by heat to securely bond the ethylene-propylene rubber sheets together in an overlap splicing procedure. A method of using the integral adhesive rubber sheeting for single-ply rubber roofing membrane or pond liners is also disclosed. Instantaneous attainment of maximum seam strength, water tightness and consistency of the seams are advantages over conventional solvent-based adhesive methods.
