Invention Title: Lightweight Multicolor Compression Molded Grip

Assignee: Eaton / Golf Pride

Abstract: A lightweight compression molded multicolor golf grip having at least a first section and a second section of differing colors and composed of elastomer compounds having a density of less than 0.90 g/cc, and joined by cross-linking across a sharply defined cross-color interface having an interface transition zone beyond which there is no mixing of the colors. The grip has a soft feel and unique compression characteristics achieved in some embodiments through the controlled use of an expanding blowing agent in a rubber compound including an EPDM mixture. Achieving the sharply defined cross-color interface is due in part to the use of complementary geometries at opposing interface edges to increase the stability of the interface and reduce the flow during molding associated with the increased viscosity of low density rubber compounds, promote cross-linking of the sections, and better distribute and control the consolidation pressure.
