摘要: A golf ball includes a core made from a rubber composition containing polybutadiene as a main rubber component and also an organic sulfur compound; and a cover made from a cover material mainly containing an ionomer resin composed of an Li ion neutralized type ionomer resin and a Mg ion neutralized ionomer resin, and also an inorganic filler having a specific gravity of 3.50 or more. A flexural amount of the core, measured by applying a load of 980 N thereto, is in a range of 4.0 to 5.5 mm. A specific gravity of the cover material is in a range of 1.020 to 1.110, and a Shore D hardness of the cover is in a range of 55 to 65. Such golf ball exhibits high durability and very high resilience.

摘要: A golf ball includes a solid core and a cover of at least one layer; wherein each of a specific gravity of the solid core and a specific gravity of the cover is nearly equal to a value (S) of a relation expression given by S=W/[(&pgr;/6)×D3], where W is a weight of the golf ball and D is a diameter of the golf ball. The golf ball can enhance the durability to increase the carry of the ball with less variations in carry of the ball.
