    摘要： An insert composed of a thermoplastic polyurethane materials is disclosed herein. The thermoplastic polyurethane insert is disposed in a recess of the club head in which the recess has a depth that is greater than the thickness of the insert. The thermoplastic polyurethane insert preferably has a plurality of tabs on its perimeter to engage the recess walls to allow the insert to essentially float within the recess. An adhesive is disposed between the rear wall of the recess and an interior surface of the insert. Further, an adhesive is applied between the plurality of tabs, and preferably over the exterior surface of each of the plurality of tabs.

    摘要： A novel composition useful for golf ball covers that comprises a blend of a diisocyanate/polyol polyurethane prepolymer with a curing agent comprising a blend of slow-reacting diamine with a fast-reacting diamine such as dimethylthio 2,4-toluenediamine and diethyl 2,4-toluenediamine, respectively. A golf ball cover made with this composition exhibits the characteristic feel and playability of a balata cover with superior durability characteristics (cut and shear resistance) which exceed those of a balata or ionomer cover.

    摘要： A golf ball having a cover composed of a polyurethane formed from a p-phenylene diisocyanate (PPDI) based polyurethane prepolymer is disclosed herein. The PPDI-based polyurethane prepolymer is formed from a PPDI and a polyol such as polycaprolactone. The PPDI-based polyurethane prepolymer is cured with a curative such as a 1,4 butane diol and glycol. The PPDI-based polyurethane cover may be either thermoset or thermoplastic. The PPDI-based polyurethane cover has a high flexural modulus at a lower hardness which gives a better feel yet maintains good distance, higher Bashore resilience, higher tensile strength, higher tear resistance, improved elongation, and better playability and control. These benefits and improvements are exhibited even though the cover of the present invention is thinner than those of conventional golf balls. The present invention also provides new golf balls having durable thin covers thereby enabling golf balls with large cores. It is well understood that increasing the core diameter of a golf ball generally translates into an increased COR which in turn generally translates into an increased initial velocity and enhanced overall travel distance.

    摘要翻译： 本文公开了具有由由对苯二异氰酸酯（PPDI）基聚氨酯预聚物形成的聚氨酯构成的覆盖物的高尔夫球。 PPDI基聚氨酯预聚物由PPDI和多元醇如聚己内酯形成。 PPDI基聚氨酯预聚物用固化剂如1,4-丁二醇和二醇固化。 基于PPDI的聚氨酯盖可以是热固性的或热塑性的。 基于PPDI的聚氨酯覆盖层具有较低硬度的高弯曲弹性模量，使其具有更好的感觉，同时保持良好的距离，更高的底板回弹性，更高的拉伸强度，更高的抗撕裂性，改善的伸长率以及更好的可玩性和控制性。 即使本发明的覆盖物比传统的高尔夫球更薄，这些益处和改进也是显现的。 本发明还提供了具有耐用的薄盖的新的高尔夫球，从而使得具有大芯的高尔夫球。 众所周知，增加高尔夫球的芯直径通常转化为增加的COR，其又通常转化为增加的初始速度和增强的总行程距离。
