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 gelling catalyst or blowing catalyst. The use of such catalyst composition improves the physical properties of the polyurethane foam.

Reactive catalyst compositions for improving water blown polyurethane foam performance

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.

An improved method of preparing polyurethane foam by reacting an organic polyisocyanate with a polyol in the presence of water and a combination of a gelling catalyst and a blowing catalyst, in which the blowing catalyst is a compound represented by the following formulae:

Group IVB metal blowing catalyst compositions for the production of

A polyurethane catalyst composition comprises N,N'-bis(3-dimethylaminopropyl) urea and 3-dimethylaminopropyl urea in a ratio that can be varied to systematically control flowability, airflow, and force-to-crush physical properties for flexible polyurethane foam to enhance processibility. Increasing the N,N'-bis(3-dimethylaminopropyl) urea to 3-dimethylaminopropyl urea ratio increases the airflow and decreases the force-to-crush values of the foam whereas decreasing the N,N'-bis(3-dimethylaminopropyl) urea to 3-dimethylaminopropyl urea ratio improves the flowability of the foam.
