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:
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:
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.

摘要:
A golf ball comprising a core comprising a center and an outer core layer surrounding the center, the center having a compression of less than about 65 and a first specific gravity; the outer core layer having a hardness of at least 80 Shore C and a second specific gravity greater than or equal to the first; and a cover disposed about the outer core layer; wherein at least one of the center or the outer core layer is formed from a fully-neutralized thermoplastic copolymer of ethylene and an α,β-unsaturated carboxylic acid, the acid being 100% neutralized by a salt of an organic acid, a cation source, or a suitable base of the organic acid; and wherein the center has a hardness less than a hardness of the outer core layer.
摘要:
A golf ball comprising an innermost core, an outer core, and a cover is disclosed. At least a layer of the golf ball is made from a low compression, high coefficient of restitution material, and is being supported by a low deformation, high compression layer. The resulting golf ball has high coefficient of restitution at high and low impact speeds and low compression for controlled greenside play.
