The golf ball comprises all known cores provided with a cover produced by a polymer blend that combines the durability of a conventional cover with excellent feel and playability. The cover formulation is a blend of various ethylene/methacrylic acid copolymers wherein at least one copolymer has a high modulus and at least one copolymer has a moderate modulus forming a miscible blend having a blend that maximizes durability while still maintaining feel and playability.

Golf ball cover material&#x2014;high resilience

A two piece golf ball has a core compression in the range of 75 PGA to 89 PGA, a core diameter in the range of about 1.535 inches to 1.545 inches, a cover hardness in the range of 42 to 60 Shore D, and a dimple pattern based on the geometry of a icosahedron. An uninterrupted equatorial great circle path, corresponding to a mold parting line, is provided in the design for forming a cover of the golf ball in two parts. A ball having such characteristics exhibits superior distance performance without compromising shot-making feel.

High performance two piece golf ball

The golf ball comprises all known cores provided with a cover produced by a polymer blend that combines the durability of a conventional cover with the feel of a traditional balata cover having a plurality of dimples in a modified dodecahedron pattern. The dodecahedron consists of twelve pentagons, which are subdivided into a total of sixty triangles. The triangles are then further subdivided into rows into which various diameter dimples are placed. The dimple pattern can be arranged to produce a pattern of ten great circles, which are free of dimples. The cover formulation is a blend of various ethylene/methacrylic acid copolymers wherein at least one copolymer has a high modulus and at least one copolymer has a moderate modulus forming a miscible blend having a PDI index that maximizes durability while still maintaining feel and playability.
