Fusabond P MD353D 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 MD353D is a chemically modified polypropylene Coupling agent, long glass-filled PP; Adhesion promoter; Coupling agent for nonhalogen, flame-retarded Wire&Cable compounds containing fillers such as aluminum trihydrate (ATH) or magnesium hydroxide (Mg(OH)2) Maleic anhydride grafted polypropylene copolymer. Possesses very high graft level. Used as a coupling agent, as an adhesion promoter, and as a coupling agent for nonhalogen, flame-retarded wire and cable compounds containing fillers such as aluminum trihydrate (ATH) or magnesium hydroxide (Mg(OH)2). Use level : 2-5 weight %.
