Hot melt adhesives based on ethylene-n-butyl acrylate

摘要

Hot melt packaging adhesive compositions consisting essentially of 35 to 45% by weight of an ethylene n-butyl acrylate copolymer containing 25-45% by weight, preferably 30 to 40% n-butyl acrylate and having a melt index of at least 50; 35 to 55% of a terpene phenolic tackifier; and 10 to 20% by weight of a high melting synthetic wax provide adhesives characterized by an excellent balance of high and low temperature performance without sacrifice to machinability or thermal stability.
