Distrupol adds Fusabond modifiers to polymer portfolio

Distrupol : 13 April, 2005  (New Product)
Distrupol, a member company of Univar and leading polymer distributor, technical service and solutions provider, has added several new grades of DuPont's range of Fusabond modifiers to the extensive portfolio of plastics materials available to its customers in the UK and Ireland. Fusabond modifiers, or coupling agents, improve both the mechanical properties and flame retardancy in halogen-free, flame retardant and low-smoke insulation and jacketing compounds used in wire and cable applications. They are supplied in a variety of base resins and are designed, primarily, for incorporation into polyethylene and polypropylene compounds.
Distrupol, a member company of Univar and leading polymer distributor, technical service and solutions provider, has added several new grades of DuPont's range of Fusabond modifiers to the extensive portfolio of plastics materials available to its customers in the UK and Ireland.

Fusabond modifiers, or coupling agents, improve both the mechanical properties and flame retardancy in halogen-free, flame retardant and low-smoke insulation and jacketing compounds used in wire and cable applications. They are supplied in a variety of base resins and are designed, primarily, for incorporation into polyethylene and polypropylene compounds.

The addition of a Fusabond coupling agent, typically, increases a wire and cable compound's tensile strength by 20-30% and elongation at break by up to 300-400%. This results in a more flexible and durable product that will allow higher filler loadings, thereby increasing the compound's flame retardancy.

'Extensive trials have shown that Fusabond coupling agents have a significant, positive influence on the physical performance and flammability characteristics of wire and cable formulations,' confirms DuPont's David Wrigley. 'Rigorous quality control ensures the modifiers have a minimal gel content to guarantee their homogeneity in the base polymer so that wire and cable extrusion lines are able to perform at their usual, very high speeds.'

'We are delighted to distribute Fusabond modifiers to our customers in the UK and Ireland,' says Andrew Canning, Commercial Manager, Distrupol UK. 'Their incorporation in wire and cable formulations provides added value for both compounders and end-users, and Distrupol is committed to providing excellence in technical support and product enhancement in order to develop their acceptance in the market.'

Resins in the DuPont Fusabond product line are modified polymers that have been enhanced, typically by maleic anhydride grafting, in order to improve their bonding performance in toughened, filled and blended compounds. The range includes Fusabond grades based on polyethylenes, polypropylenes, ethylene vinyl acetates, ethylene propylene rubbers and ethylene acrylate copolymers.

Flame retardant fillers such as alumina trihydrate and magnesium hydroxide show a particular affinity to Fusabond maleic anhydride grafted resins. Property improvements are also achieved when Fusabond is in combination with more common fillers, such as calcium carbonate.
