Latest Patents

Keller holds a patent for "Solid polyurethane elastomers which exhibit reduced dimensional shrinkage." This invention relates to solid elastomers that demonstrate reduced dimensional shrinkage and outlines a process for their production. The elastomers consist of the reaction product of a polyisocyanate component or prepolymer, combined with an isocyanate-reactive component. This component includes a high molecular weight element with an EO cap of less than 17% by weight, a chain extender, and optionally, a crosslinker, all produced in the presence of at least one catalyst. The solid elastomers are manufactured through a reaction injection molding process in a closed mold, ideally at an isocyanate index ranging from about 70 to about 130. Keller's innovative approach has resulted in a patent count of 1 patent.
