DuPont™ Fusabond®

Resins in the DuPont™ Fusabond® product line are modified polymers that have been functionalized (typically by maleic anhydride grafting) to help bond together dissimilar polymers used in toughened, filled and blended compounds. The product line includes modified ethylene acrylate carbon monoxide terpolymers, ethylene vinyl acetates (EVAs), polyethylenes, metallocene polyethylenes, ethylene propylene rubbers and polypropylenes.
