摘要:
This invention is related to multi-layer golf balls having an inner cover layer comprising a blend of styrene-block copolymer and trans-polyisoprene, an outer cover layer comprising a polyurethane, a polyurea or a mixture thereof, and a core comprising of thermosetting or thermoplastic materials.
摘要:
A high performance golf ball having a reduced overall distance while maintaining the appearance of a high performance trajectory. The golf ball includes a combination of low CoR core and cover materials coupled with a less aerodynamic dimple pattern that achieves a reduction in carry and overall distance of 15 and 25 yards versus a conventional golf ball, while still providing the look, sound, feel and apparent flight of a conventional golf ball. A high performance golf ball having a reduced distance is also achieved by controlling dimensionless coefficients of lift/weight and drag/weight at certain Reynolds numbers and spin ratios for various CoR.
摘要:
A golf ball comprising at least a core, a cover layer and optionally at least one intermediate layer disposed between the core and the cover layer. At least a layer of the golf ball is formed from a polymer composition comprising peroxide-cured diene rubber formulations that are substantially free of ZDA.
摘要:
The present invention is directed to golf balls having at least one layer formed from a rubber composition comprising a base rubber and from 5 to 100 parts of an oily substance, by weight per 100 parts of the base rubber. The rubber composition may be present in any one or more of a core layer, a cover layer, or an intermediate layer.
摘要:
The present invention is directed to golf balls having a resilient inner core and outer core made of a material substantially free of fillers. The invention also encompasses golf balls wherein the inner and outer cores are not made of a thermoplastic material. The invention encompasses golf balls having an inner core, an outer core, an inner cover, and an outer cover wherein the inner core has a specific gravity ρ12, the outer core has a specific gravity ρ14, the inner cover has a specific gravity ρ16, and the outer cover has a specific gravity ρ18, wherein the relationship between the specific gravities is expressed by the mathematical expression: ρ16≧ρ18≧ρ14≧ρ12.
摘要:
The present invention provides high moment of inertia golf balls comprising a low specific gravity core layer formed from a moisture resistant composition. The moisture resistant composition has a moisture vapor transmission rate (MVTR) of 12.5 g·mil/100 in2/day or less and comprises a highly neutralized acid polymer. Golf balls of the invention have a moment of inertia of 85 g·cm2 or greater.

摘要:
A golf ball including a core formed from a halogenated thiophenol and having a diameter of 1.30 inches to 1.40 inches, a compression of 45 or less; and a coefficient of restitution of 0.780 or greater at 125 ft/s; and a cover having a thickness of 0.14 inches to 0.16 inches and being formed from a composition comprising a Na-ionomer and a Li-ionomer blend having a Shore D hardness of 60 to 70; wherein a combination of the core and the cover results in the golf ball having a compression of 85 to 95, and a coefficient of restitution of 0.815 to 0.825 at about 125 ft/s.
摘要:
The present invention relates generally to golf balls containing a centipede polymer in one or more core layers, one or more cover layers, one or more intermediate layers.
摘要:
The present invention is directed towards a multi-layered core golf ball that comprises a thermoplastic inner casing layer molded between two core layers to create a faster golf ball with less spin, by designing a ball that has more of the stored energy of the core released at impact. One inner casing layer and/or an outer core layer is comprised of a partially or fully neutralized ionomer.
摘要:
The present invention is directed to multi-layer golf balls having a center, a cover layer, and at least one intermediate layer between the core and the cover layer. The core, the at least one intermediate layer and the cover are constructed to have different initial velocities and COR such that the gradient of the initial velocities and COR progress from a faster center to a slower cover.
