Abstract:
1. A hot melt adhesive comprising: an ethylene vinyl acetate having 18-33 wt % of vinyl acetate and a melt index of 3 -800 dg/min and/or ethylene n-butyl acrylate having 28-35% of n-butyl acrylate, and a melt index of 60-900 dg/min, 10 to 25 wt % of a soy wax with a melting point from 130° F. to 190° F., 15 to 25 wt % of a synthetic wax with a melting point from 140° F. to 250° F., and a tackifier selected from the group consisting (i) C5 modified C9 with at least 25% of aromatic carbons and with a softening point from 90° C. to 150° C., (ii) a terpene phenolic rosin with a softening point from 120° C. to 150° C., (iii) a rosin ester with a softening point from 100° C. to 140° C. and (iv) mixtures thereof; and wherein the adhesive has a set speed of 5 seconds or less and a heat resistance of 130° F. or greater.
