HOT MELT ADHESIVE COMPOSITION

摘要

An adhesive composition is described that is particularly useful for application to the plastic nonwoven materials found in personal hygienic articles. The composition includes first and second ethylene vinyl acetate copolymers. The first copolymer has a high molecular weight characterized by a melt viscosity at 150° C., of 100 Pascals per second or more. The second copolymer has a low molecular weight characterized by a melt viscosity at 150° C. of 50 Pascals per second or less. The second copolymer is present in an amount by weight percent less than or equal to the amount by weight percent of the first ethylene vinyl acetate copolymer. The composition also includes at least one tackifier resin, a hydrocarbon wax present in an amount from 0.5% to 10% by weight of the composition; and, a liquid plasticizer present in an amount up to 20% by weight of the composition.
