摘要:
A molded rubber material for a golf ball is obtained by molding and vulcanizing a rubber composition composed of (a) a diene rubber, (b) an α,β-unsaturated carboxylic acid and/or a metal salt thereof, (c) an organic peroxide, and (d) an inorganic oxide. The inorganic oxide is prepared by a plasma process, a laser process or flame synthesis, has an average particle size of at most 200 nm, and is added in an amount of at least 1 wt % based on the zinc acrylate. The molded rubber material has a high hardness, a good resilience, and excellent durability.
