| DuPont has recently launched a new cost-effective, medium performance copolymer for the modified polymer industry. Branded Fusabond� AEB-560D, the new product is a chemically modified ethylene acrylate copolymer that provides a more economical functionalised ethylene copolymer for polyamide (PA) modification than standard grafted copolymer technology. The new product delivers comparable toughness versus traditional maleic anhydride acrylate terpolymer tougheners; however, it also provides additional performance attributes. It improves mould flow, produces less reduction in flexural modulus than incumbent intermediate tougheners. It also provides surface finish advantages, and creates a more cost-effective toughener that maintains its resiliency from room temperature to -20�C.
In addition, Fusabond� AEB560D can be utilised 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 new product provides a medium level of performance in helping compounders boost toughness and incorporate glass fibre and other fillers into a wide range of plastics.
