HFFR Coupling with DuPont™ Fusabond®

HFFR coupling in composite panel core compounds, as well as wire and cable jacketing, can be reliably achieved using DuPont™ Fusabond® functionalized polyolefins. Fusabond® coupling agents are especially helpful in highly mineral-filled compounds such as polyolefin matrices needing high concentrations of Mg(OH)2 or ATH.

DuPont™ Fusabond® HFFR coupling agents enable efficient building panel core layer compounds incorporating high mineral filler loadings.

When compared with silane coupling agents or other grafted polyolefins, Fusabond® provides:

• superior tensile strength and elongation at break of finished compounds;
• lower gel content, for higher compound performance consistency; and
• very low water absorption of finished compounds.

By combining superior compounding performance and consistent quality, DuPont™ Fusabond® can often be used in lower concentrations to achieve required properties a cost-effective filled compound.
