摘要:
A golf ball exhibits a high spin and easily comes to a halt even when shot from the rough or when shot in a raining condition. The cover material of the golf ball is based on ionomer resin. The cover material has 5-50 parts by weight of a tackifier such as terpene resins, rosin ester resins or the like blended with respect to 100 parts by weight of the base material.
摘要:
A rubber composition suitable for use in grips of articles such as golf clubs, tennis rackets, bicycles and tools, comprising (1) a rubber component containing an ethylene-propylene-diene rubber (EPDM), and (2) 5 to 100 parts by weight of a polyisobutylene having a viscosity average molecular weight of 6,000 to 50,000, which provides grips having good feeling of touch, good non-slipping properties in both fine and rainy weather, and giving a small feeling of impact to mis-shot of golf balls as compared with conventional grips.

Disclosed is a golf ball comprising a core 1 composed of a center 1a and an outer shell 1b, and a cover 2 covering said core 1, wherein a specific gravity of said center 1a is 0.2 to 1. The golf ball has excellent flying distance and satisfies other performances of golf balls.
摘要:
The present invention provides a three-piece solid golf ball having both excellent hit feeling and large flying distance. The three-piece solid golf ball comprises a core 1 and a cover 2 covering the core 1, and the core 1 has a two-layer structure comprising a center 1a and an outer shell 1b. The center 1a contains an .alpha.,.beta.-unsaturated carboxylic acid metallic salt in an amount of 13 to 28 parts by weight based on 100 parts by weight of a base rubber and the outer shell 1b contains an .alpha.,.beta.-unsaturated carboxylic acid metallic salt in an amount of 28 to 35 parts by weight based on 100 parts by weight of an base rubber. A surface hardness (measured by JIS-C type hardness tester) of the core 1 is 75 to 88 and a compression deformation amount of the core 1 is 2.7 to 5.0 mm.
