Disclosed are a process of producing a polyurethane foam product, a polyurethane foam product pre-mix, polyurethane foam product formulation, and a polyurethane foam product. The process of producing the polyurethane foam product includes contacting a halohydrin component with a polyurethane foam product pre-mix. The polyurethane foam product pre-mix includes the halohydrin component. The polyurethane foam product formulation includes a polyol component, an isocyanate component, and a halohydrin component. The polyurethane foam product is formed by the pre-mix having the halohydrin component.

Polyurethane foam production process, pre-mix, formulation, and product

The present invention provides trimerization catalyst compositions having a sterically hindered carboxylate salt used in combination with a tertiary amine catalysts having isocyanate reactive groups and methods to produce a polyisocyanurate/polyurethane foam using such trimerization catalyst compositions.
