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 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. 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.

Lightweight multicolor compression molded grip

A golf grip composed of multiple rubber compounds producing desirable properties within the golf grip.

Golf grip

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. 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.

The present disclosure thus provides a unique flexible elastomeric grip for an implement handle such as a shaft of a golf club and has a pattern of voids/recesses in the form of grooves and/or dimples on the inner periphery thereof which may be spaced to provide different cushioning in longitudinally spaced regions of the grip. Where texture grooves are employed on the outer periphery of the grip of the present disclosure, the thickness of the material between the grooves and/or dimples on the inner periphery and the texture on the outer periphery is maintained at not less than one millimeter (1 mm).

Flexible implement grip with interior texture

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.
