摘要： Two and three piece golf balls having improved rebound characteristics include cores and centers, respectively, that are comprised of polybutadiene rubber and inorganic fillers with specific gravities of about 5.4 or greater. The inorganic fillers may be selected from tungsten, bismuth, copper, bismuth oxide, nickel, cobalt, iron, steel, tin, chromium, zinc, bismuth subcarbonate, cupric oxide, barium tungstate, cuprous oxide or ferrous oxide.

摘要： A three piece golf ball (1) has a center compression in the range of about 40 PGA to 60 PGA, a center (5) weight in the range of about 27.5 grams to 28.5 grams, a core (6) compression in the range of about 60 PGA to 80 PGA, a core weight in the range of about 34.5 grams to 35.5 grams, a cover (2) hardness in the range of 63 to 69 Shore D, and an ionomer cover composition wherein the ionomer mixture comprises a blend of about 75 % by weight of a high resilience ionomer and about 25 % by weight of a very low modulus ionomer. In addition, the present invention provides a golf ball (1) having a plurality of dimples (200, 202, 204), of about 402 in number, arranged on its outer surface, selected from two sets of dimples, the first set having a single radius cross section, and the second set having a dual radius cross section. The dimple configuration of the instant invention is based on the geometry of a rhombicosadodecahedron. A ball having such characteristics exhibits superior distance performance without compromising shot-making feel.

摘要： A two piece golf ball (5) has a core compression in the range of 67 PGA to 77 PGA, a core diameter in the range of about 1.535 inches to 1.545 inches, a cover hardness in the range of 65 to 71 Shore D, and a dimple pattern based on the geometry of a rhombicosadodecahedron. An uninterrupted equatorial great circle path, corresponding to a mold parting line (30), is provided in the design for forming a cover (4) of the golf ball in two parts. A ball having such characteristics exhibits superior distance performance without compromising shot-making feel.
