DuPont’s Fusabond AEB-560D is a new copolymer that will help compounders boost toughness and incorporate glass fibre and other fillers into a wide range of plastics.

Targeted at the modified polymer industry, the new product is a chemically modified ethylene acrylate copolymer that, DuPont claims, provides a more economical functionalised ethylene copolymer for polyamide (PA) modification than standard grafted copolymer technology.

The company adds that AEB-560D resin delivers comparable toughness versus traditional maleic anhydride acrylate terpolymer tougheners. However, it also improves mould flow, produces less reduction in flexural modulus than incumbent intermediate tougheners, provides surface finish advantages, and creates a more cost-effective toughener that maintains its resiliency from room temperature to – 20 degrees C.

In addition, it can be used in other applications to function as a coupling agent, compatibiliser and impact modifier in a wide assortment of resin systems. One of these potential applications is the use as a coupling agent in halogen-free flame retardant thermoplastic wire and cable compositions.

The latest addition to the DuPont family of nylon modifiers, Fusabond AEB-560D complements the company’s present line of high-performance modifiers: MF-416D, MN-493D and MN-494D.

DuPont manufactures Fusabond grades using a variety of base resins and graft levels. Resins in the DuPont Fusabond product line are modified polymers that have been functionalized (typically by maleic anhydride grafting) to help bond polymers used in toughened, filled and blended compounds.

The product line includes modified ethylene acrylate copolymers, ethylene acrylate carbon monoxide terpolymers, ethylene vinyl acetates (EVAs), polyethylenes, metallocene polyethylenes, ethylene propylene rubbers and polypropylenes.
