Fusabond P M613-05 Maleic anhydride grafted polypropylene 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® P M613-05 is a chemically modified polypropylene Coupling agent, short glass-filled PP Maleic anhydride grafted polypropylene homopolymer. Possesses medium graft level. Used as a coupling agent. Use level : 2-5 weight %.
