Patent ID: 8324309

Claim:
A non-woven assembly adhesive comprising: from about 20 to about 30 wt. % of styrenic block copolymer, from about 40 to about 70 wt. % of tackifier resin, and from about 5 to about 40 wt. % of plasticizer, all based on 100 wt % of the non-woven assembly adhesive, said styrenic block copolymer having the formula of (S−S/B) n X, wherein S represents a polymer block of styrene and S/B represents a polymer block obtained by random copolymerization of a mixture of styrene and butadiene in a weight ratio in the range of from 2:98 to 30:70, and said styrenic block copolymer has a total apparent molecular weight from 20,000 to 150,000 g/mol, wherein n is an integer in the range of from 1 to 5, wherein X is the remainder of the coupling agent; and said styrenic block copolymer has a melt flow rate ranging from 40 to about 60 g/min., at 200° C./5 kg; said tackifier is selected from C5-C9 hydrocarbon resin; and said plasticizer is an oil compatible with said styrenic block copolymer and said tackifier resin.
