Abstract
The present invention provides a reactive catalyst composition for making a water blown flexible polyurethane foam. The catalyst composition comprises a tertiary amino alkyl urea and/or bis(tertiary amino alkyl) urea in combination with either a tertiary amine gelling catalyst or a tertiary amine blowing catalyst. The use of such catalyst composition improves the physical properties of the polyurethane foam.
