Abstract:
Polyurethane carpet backings are made using a polyurethane-forming composition that includes hydroxymethyl-containing polyester 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 good curing rates.
