  • Patent number: 11912906
    Abstract: A hot melt adhesive composed of an ethylene vinyl acetate copolymer, a hydrogenated styrenic block copolymer, a tackifying resin, and a liquid plasticizer. The preferred ethylene vinyl acetate copolymer has a vinyl acetate content between 8 and 28 percent by weight, and the preferred hydrogenated styrenic block copolymer is a styrene-ethylene-butylene-styrene having about 30% styrene content and essentially no diblock. The hot melt gives excellent peel strength when used as a construction adhesive for disposable nonwoven articles. It can also be formulated to exhibit very low bleed through and blocking characteristics when used on low basis weight nonwoven fabrics.
    Type: Grant

  • Patent number: 11261355
    Abstract: A hot melt adhesive composition, which may be used as a construction adhesive in hygiene articles, comprises a first polymer comprising a unimodal copolymer of propylene and ethylene and having a weight average molecular weight of between about 5,000 and 60,000 daltons; a second polymer comprising a copolymer of propylene and ethylene and having a weight average molecular weight of at least 100,000 daltons; a tackifying resin having a Ring & Ball softening point of at most 115° C.; and a plasticizer. The composition demonstrates good peel strength and good shear resistance and is sprayable, with a sufficiently low viscosity, at low application temperatures, such as at about 121° C.
