Composite Paneling with HFFR Coupling Achieved with DuPont Fusabond®
Composite paneling with Halogen Free Flame Retardant (HFFR) coupling in 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.
HFFR Coupling Efficiency
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.
