    • The present invention is directed to improved multi-layer golf ball compositions having a core, an inner cover and an outer cover and the resulting regulation balls produced using these compositions. In this regard, a smaller and lighter core is produced and metal particles, or other heavy weight filler materials, are included in the inner cover compositions. This results in a molded golf ball exhibiting enhanced interior perimeter weighting. the heavy weight filler particles, such as powdered metals, are included in a relatively thick inner cover layer (or mantle) formed from an ionomer resin of a solid, three-piece multi-layered golf ball. The size and weight of the core can thereby be reduced in order to produce an overall golf ball which meets, or is less than, the 1.62 ounce maximum weight limitation specified by the United States Golf Association. It has been found that the combination of the present invention produces a golf ball with an increased moment of inertia and/or a greater radius of gyration and thus generates lower spin due to the increased weight of the inner cover layer. This results in a golf ball exhibiting enhanced distance without substantially effecting the feel and durability characteristics of the ball.
    • 本发明涉及具有芯,内盖和外盖的改进的多层高尔夫球组合物,以及使用这些组合物制成的调节球。 在这方面,产生较小且较轻的芯,并且内盖组合物中包括金属颗粒或其它重质填料材料。 这导致显示增强的内部周长加权的模制高尔夫球。 诸如粉末金属的重质填料颗粒被包括在由固体三片多层高尔夫球的离聚物树脂形成的相对较厚的内覆层(或地幔)中。 因此,可以减小芯的尺寸和重量,以便产生满足或小于美国高尔夫协会规定的最大重量限制为1.62盎司的整体高尔夫球。 已经发现,本发明的组合产生具有增加的惯性矩和/或更大的回转半径的高尔夫球,并且由于内覆盖层的重量增加而产生较低的旋转。 这导致高尔夫球表现出增强的距离,而基本上不影响球的感觉和耐久性。
