Fusabond N MN493D Maleic anhydride grafted ethylene octene copolymer DuPont Fusabond® maleic anhydride grafted resins can be used as coupling agents between polymers -- mainly polyolefins such as polyethylene and polypropylene -- and fillers, in order to increase the filler acceptability of polymers. Typical levels of Fusabond® are in the range of 2-5 weight % based on the entire compound. Fillers that show an affinity to Fusabond® maleic anhydride grafted resins include flame-retardant fillers, such as alumina trihydrate (ATH) and magnesium hydroxide (Mg[OH]2). Improvement in properties also can be seen when Fusabond® is used in combination with common fillers such as calcium carbonate. Fusabond® N MN493D is a chemically modified ethylene octene copolymer nylon modifier PA6 toughener; PA6,6 toughener Maleic anhydride grafted ethylene octene copolymer. Possesses medium graft level. Used as a nylon modifier, toughener. Use level : 2-5 weight %.
