The invention relates to an elastomeric hot melt adhesive in the form of a stable foam which can be used to elasticate structures such as absorbent articles which can be applied without the use of any glue. A hot melt adhesive composition is used as the basis for the foam, which composition comprises at least one thermoplastic elastomer and at least one tackifying resin, the thermoplastic elastomer(s) being a styrene/butadiene/styrene (SBS) copolymer or a blend of styrene/butadiene/styrene (SBS) copolymer with styrene/ isoprene/ styrene (SIS) in which SIS is present in an amount equal to or less than 50% by weight of the total block copolymer, and wherein the hot melt adhesive composition is further characterized in that: a) it is capable of bonding, when applied from the molten state, to plastic and/or cellulosic materials with a 90° peel force of not lower than 0.5 N/cm (as herein defined); it has a tensile strength retention after 50 cycles (as herein defined) of at least 40%; and c) it has a viscosity of 120,000 cps or less at 180°C and an applied shear of 80 sec-1.
