COMPOSITION OF THERMAL MELT ADHESIVE

摘要

Melt-fusion adhesive composion changes little with the wide range of temperature. The composition comprises ethylene-vinyl acetate copolymer, adhesive agent and antioxidants. In addition, liquid- phase polyisoprene rubber and A-B-A type block copolymer are also added to the composition, where A is vinyl aromatic hydrocarbon polymer block, and B is dien polymer block. Average molecular weight of isoprene is 5,000-50,000. Ten-50 wt. pts acetate copolymer. The above A-B-A type block copolymer is styrene- ethylene/butyrene-styrene and the radio of styrene to rubber is (13-30):(70-87).
