REACTIVE HOT MELT ADHESIVE

WIPO Patent Application WO2004076507

A3

A reactive hot melt composition in the form of free-flowing pellets. The composition comprises from 37 to 60% based on the total weight of the composition of a cross-linkable resin including at least one copolymer of ethylene with an ethylenically unsaturated monomer and wherein the cross-linkable resin includes an ethylene-acrylic acid or ethylene-methacrylic acid copolymer, from 10 to 30% based on the total weight of the composition of an adhesion promoter, which is a plasticiser and/or a tackifier, for providing adhesive properties to the composition at temperatures of from 50 to 100°C, from 0.5 to 3% based on the total weight of the composition of a free radical cross-linking initiator having a 1 hour half-life temperature of from 110 to 170°C, from 10 to 40% based on the total weight of the composition of a filler and from 0.1 to 4% based on the total weight of the composition of a foaming agent.
