<p>PURPOSE:To provide the two-piece golf which is soft in feeling at the time of hitting, and also, excellent in durability (shock resistance) and repellency. CONSTITUTION:The two-piece golf ball consists of a two-layer structure of a core of the center part and a cover its outside, and the core is constituted of a core material whose compression value at the time of deformation of 2.54mm is <=50kgf, and also, the cover is constituted of a cover material whose tensile elongation and 50% modulus are >=400%, and >=1.5kgf/mm<2>, respectively, and the compression value at the time of deformation of 2.54mm is <=95kgf.</p> |
