摘要:
An adhesive and method for hot melt application. The adhesive comprises polyolefin base polymer, from 1 to 10 wt % of at least one functionalized polyolefin, and from 1 to 15 wt % of a wax, based on the total weight of the polyolefin base polymer, functionalized polyolefin and wax, wherein the wax has a weight average molecular weight at least 8% of the weight average molecular weight of the polyolefin base polymer, viscosity at 190° C. of 60 mPa·s or more, and a crystallization temperature greater than the polyolefin base polymer and greater than 100° C., and wherein the adhesive has at least 5% fiber tear at 2° C., at least 50% fiber tear at 25° C., and a characteristic set time of less than 3 seconds.
