LOW APPLICATION TEMPERATURE HOT MELT WITH EXCELLENT HEAT AND COLD RESISTANCE

摘要

A hot melt useful for packaging comprising: a) from about 10 % to about 40 % by weight of a block copolymer; b) up to about 20 % of a compatible polymer wherein the total polymer content does not exceed 40 % by weight; c) from about 25 % to about 60 % by weight of at least one tackifying resin; d) from about 5 % to about 25 % by weight of a compatible plasticizer; and e) from about 10 % to about 40 % by weight of at least one wax component wherein the viscosity of the hot melt adhesive is less than about 1500 cPs at about 150 ~C.
