Distrupol adds Fusabond modifiers to polymer portfolio
Several new grades of-DuPont’s range of Fusabond® modifiers have been added to Distrupol’s portfolio of plastics.
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.”
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.
