Abstract
A method of improving the physical properties of high density reinforced reaction injection molded microcellular or solid elastomers is disclosed. The method involves placing an inert filler material wholly in the isocyanate component of a two component reaction system where the other component contains predominantly polyol before mixing the components to effect reaction. This modification will result in an improvement in tensile strength and thermal dimensional stability when compared to placing the inert filler material in the polyol component before reaction.
