The present invention relates to a golf ball made by mixing 0.5-60 parts by weight of a bismuth or bismuth alloy or a bismuth alloy with a bismuth alloy with respect to 100 parts by weight of an organic polymer resin, which is used as a base material for making golf balls, in the resin composition. This is to improve the distance more than the usual golf ball without increasing the hardness than necessary. This is because the organic polymer material, which is the base material by the expanded ratio, is formed by forming the resin composition using the bismuth or bismuth alloy and expanding it by 3-3.5% when the bismuth or bismuth alloy solidifies when cooled to room temperature. This is because it becomes more dense and contains a lot of energy. In addition, it can be applied to all the nucleus and the cover, or can be selectively applied to each part to create a golf ball having a variety of different characteristics to satisfy a variety of golfers. In addition, the golf ball according to the present invention has a soft characteristic, the feel is good. |
