DuPont Corp. recently introduced low-gel coupling agents for production of improved halogen-free insulation and jacketing for wire and cable.

The Fusabond modifiers enable compounders to improve both mechanical properties and flame retardancy by allowing increased filler levels in halogen-free, flame retardant and low-smoke insulation and jacketing compounds used in wire and cable constructions.

The agents increase the tensile strength 20-30% in its unaged state as well as after aging in air or in an oil environment. The result, the company says, is a more flexible and durable product, which allows higher filler loadings so better flame retardancy can be achieved due to higher filler acceptability of the base polymer.
