| 20080254915 | GOLF BALL - A two-piece golf ball having a reaction injection molded polyurethane cover is disclosed herein. The golf ball has a core with a diameter preferably ranging from 1.610 inches to 1.670 inches, and a cover having a thickness preferably ranging from 0.015 inch to 0.045 inch. The cover also preferably has a plurality of deep apertures extending through the cover. | 10-16-2008 |
| 20090069117 | REACTION INJECTION MATERIAL FOR A GOLF BALL - A golf ball having a layer composed of a polyurethane/polyurea material formed from reaction injection molding a polyol component and an isocyanate component. The polyol component preferably comprises a polytetramethylene ether glycol having a molecular weight of approximately 1000 and a 3,5-diethyl-2,4 toluenediamine. The layer is preferably a cover layer having a thickness ranging from 0.010 inch to 0.025 inch. | 03-12-2009 |
| 20090156331 | GOLF BALL - A two-piece golf ball having a reaction injection molded polyurethane cover is disclosed herein. The golf ball has a core with a diameter preferably ranging from 1.610 inches to 1.670 inches, and a cover having a thickness preferably ranging from 0.015 inch to 0.045 inch.

| 20090203468 | GOLF PRODUCTS PRODUCED BY A STOICHIOMETRICALLY IMBALANCED RIM SYSTEM - Disclosed herein are golf products, such as golf balls and/or components thereof, including the product of a fast-chemical-reaction mixture comprising a polyol and an isocyanate. The component is formed by reaction injection molding the reaction mixture. In the reaction mixture, the stoichiometry of the reactants is imbalanced. | 08-13-2009 |
| 20090203470 | MULTI-LAYER GOLF BALL - A golf ball comprises a molded core, one or more ionomer mantles, and a thermoset polyurethane cover. The core is a high cis-polybutadiene crosslinked with zinc diacrylate and may also comprise a halogenated thiophenol and metal thiosulfate. One or more of the ionomer mantles comprises an ionomer neutralized to 80% or greater. | 08-13-2009 |
| 20100015351 | METHOD FOR TREATING THERMOPLASTIC POLYURETHANE GOLF BALL COVERS - A method of forming a golf ball is disclosed herein. The method includes placing a golf ball precursor product with a thermoplastic polyurethane cover in a solution containing an isocyanate functionality reactive material. The precursor product is then removed from the solution and heated to remove solvent. The precursor product is then placed in an isocyanate solution. The precursor product is then removed and heated to remove solvent to prepare the precursor product for finishing. | 01-21-2010 |
| 20100035705 | METHOD FOR TREATING THERMOPLASTIC POLYURETHANE GOLF BALL COVERS - A method of forming a golf ball is disclosed herein. The method includes placing a golf ball precursor product comprising a thermoplastic polyurethane cover further comprising an isocyanate or hydroxyl terminated polybutadiene in an isocyanate solution. The precursor product is then removed and heated to remove solvent. The precursor product may then be subjected to gamma or electron beam irradiation. | 02-11-2010 |
| 20100084789 | GOLF PRODUCTS PRODUCED BY A STOICHIOMETRICALLY IMBALANCED RIM SYSTEM - Disclosed herein are golf products, such as golf balls and/or components thereof, including the product of a fast-chemical-reaction mixture comprising a polyol and an isocyanate. The component is formed by reaction injection molding the reaction mixture. In the reaction mixture, the stoichiometry of the reactants is imbalanced. | 04-08-2010 |
| 20100330285 | METHOD FOR TREATING THERMOPLASTIC POLYURETHANE GOLF BALL COVERS - A method of forming a golf ball is disclosed herein. The method includes placing a golf ball precursor product with a cover comprising a thermoplastic polyurethane material and a dendritic polymer in a solution containing an isocyanate functionality reactive material. The precursor product is then removed and heated to remove solvent to prepare the precursor product for finishing. | 12-30-2010 |
