DuPont modifiers for improved wire and cable compound performance

Making its debut at Wire 2008, Fusabond® N525 is the latest offering for the HFFR compound market. “Poor flexibility is a common drawback with HFFR cables. By replacing existing coupling agents with Fusabond® N525 the compound flexibility is significantly improved while other properties like strength and elongation are maintained,” says Gustav Jannerfeldt, market segment leader for wire and cable at DuPont Packaging & Industrial Polymers.

Fusabond® N525 has the same high and consistent quality level as other Fusabond® grades currently used in the wire and cable industry. “The compound properties are strongly related to the coupling agent and any quality inconsistencies of the coupling agent may result in cable failure later on,” explains Jannerfeldt.

Apart from presenting its new coupling agents, DuPont Packaging & Industrial Polymers is also promoting the use of Elvaloy® ethylene based terpolymers in HFFR cables. By adding highly polar Elvaloy® terpolymers to the compound, both oil- and chemical resistance as well as low temperature flexibility are improved. Processing short comings normally associated with highly polar high VA content EVAs, such as blocking of pellets, are not present with Elvaloy®.
