Patent ID: 7838590

Claim:
A hot melt adhesive composition, comprising a blend of the following components: about 1% to about 20% by weight of a styrene-ethylene-ethylene-propylene-styrene random block copolymer; about 10% to about 70% by weight of a first midblock tackifying resin having a softening point of about 85° C. to about 125° C.; about 0% to about 65% by weight of a second midblock tackifying resin; about 5% to about 60% by weight of a plasticizer; and about 0% to about 20% by weight of an end block reinforcing resin having a softening point equal to or higher than 115° C.; wherein the components total 100% by weight of the composition, and the viscosity of the composition is equal to or less than about 20,000 mPa·s at 160° C.
