| 473367000 | Interior includes injected or compressed material | 10 |
| 20080312007 | Highly Neutralized Polymeric Compositions for Golf Ball Layers - Compositions for golf balls including modified highly neutralized polymeric compositions that have improved processability including improved melt flow index and improved performance characteristics when included in a layer of a golf ball. In addition, the compositions of the invention have less moisture transmission and higher flexural modulus than non-modified highly neutralized polymers. | 12-18-2008 |
| 20090098950 | MOLD FOR FORMING GOLF BALL - There are provided a golf ball molding die capable of manufacturing a golf ball having a satisfactory surface condition, and a golf ball manufactured by using the die. The present golf ball molding die comprises at least two die bodies within which a cavity for molding a golf ball is formed by jointing of the die bodies; and a pin accommodating hole provided in at least one of the die bodies, and is characterized in that at least one groove communicating directly with the cavity is provided in the wall surface of the pin accommodating hole. | 04-16-2009 |
| 20090247322 | GOLF BALL - The invention provides a golf ball having a ball component made of a material molded under heat from a rubber composition of (a) a base rubber which includes a polybutadiene of at least 40% cis-1,4 structure, (b) an unsaturated carboxylic acid and/or a metal salt thereof, (c) an organic peroxide, and (d) a halogenated thiophenol, and/or a metal salt thereof, which is prepared by reacting starting materials in a polar solvent then washing with water and drying. The golf ball of the invention uses as a ball component a material of exceptional resilience which is obtained by molding a rubber composition under applied heat. As a result, the ball as a whole has an excellent rebound. | 10-01-2009 |
| 20130296072 | GOLF BALL - The invention provides a golf ball having a core and a cover of at least one layer. The core has a cross-sectional hardness which, letting (H | 11-07-2013 |

| 20090011854 | REACTION INJECTION MOLDABLE COMPOSITIONS, METHODS FOR MAKING SAME, AND RESULTANT GOLF ARTICLES - The invention relates to a method for forming golf equipment, or a portion thereof, preferably for forming one or more layers of a golf ball, including: providing a first reactable component containing an isocyanate-containing compound, and a second reactable component containing at least one polyol, polyamine, or epoxy-containing compound; mixing the reactable components together to form a reactive mixture; and injecting the reactive mixture into a cavity or mold having a desired shape within a time sufficient to avoid substantial polymerization, gelation, or solidification. Alternately, instead of providing an isocyanate-containing reactable component and at least one polyol, polyamine, or epoxy-containing compound, the method may include providing at least two sets of precursor components that can be reacted to form at least two different polymers of an interpenetrating polymer network, at least one polymer being crosslinked, wherein, if any of the at least two component sets include a mixture of precursor components, then that mixture must be sufficiently non-reactive such that the sets of precursor components, when placed in contact with each other, can still form an interpenetrating polymer network. | 01-08-2009 |
| 20100004069 | GOLF BALL HAVING CO-INJECTED BI-MODAL ETHYLENE-ACID COPOLYMER DUAL LAYER COVER - A golf ball having a cover comprising thin inner and outer layers formed by a co-injected cup process. The inner layer comprising a hard Surlyn while the outer layer comprises a composition a bi-modal ethylene-acid copolymer composition. The core size will be greater than 1.50 inches in diameter. The golf ball will provide a cover that is compression molded and is very soft without sacrificing durability or shear resistance. The outer layer comprising a bi-modal ethylene-acid co-polymer composition. | 01-07-2010 |
| 20130225322 | Ball Incorporating Cover Separation Element - A ball includes a core, a cover, and an intermediate layer between the core and the cover. The intermediate layer may be deformed or actuated to create discontinuities in the cover. The creation of discontinuities allows for easier recycling of the ball parts. The intermediate layer may include one of a bladder or a hydrophilic material that expand upon the introduction of a fluid, a shape memory polymer that deforms upon application of a stimulus, or two materials that react chemically to form a gas. | 08-29-2013 |

| 20130225323 | Multi-Layer Golf Ball With Bladder Core - The present disclosure is directed to a golf ball and a method for manufacturing a golf ball including a bladder core. In at least one embodiment, the bladder core includes an ethyl vinyl alcohol copolymer layer combined with multiple layers of thermoplastic polyurethane or other material to prevent leakage. In addition, it is contemplated that the bladder core may include a one-way valve for adjusting the pressure of a fluid within the bladder core to produce different performance characteristics. | 08-29-2013 |
| 473370000 | Diverse layer between shperical core and cover | 1 |
| 20110319191 | Golf Ball With Precompressed Medial Layer - A golf ball is made from a plurality of layers. A core is formed of a soft material. A medial layer surrounds the core and is formed of a precompressed rubber. A cover surrounds the medial layer. A compression layer may be used to precompress the medial layer. | 12-29-2011 |
