CA 2566626

Polyurethane carpet backings are made using a polyurethane-forming composition that includes fatty acid amide polyols. The formulation allows a significant replacement of conventional polyols with polyols derived from annually renewable resources, while maintaining important properties like edge curl, tuftbind, viscosity and curing rates.

Cette invention concerne des endos de moquette en polyuréthane que l'on réalise en utilisant une composition de formation de polyuréthane englobant des polyols d'amide d'acide gras. La formulation permet de remplacer en proportion notable les polyols conventionnels par des polyols dérivés de ressources annuellement renouvelables, tout en préservant des propriétés importantes comme la résistance au gondolement, la résistance des touffes à l'arrachement, la viscosité et la vitesse de durcissement.
