A golf ball comprising a core comprising an inner core center and an outer core layer disposed over the inner core center. The inner core center has a deflection of greater than 0.210 inch under a load of 100 kilograms, and the entire the core has a deflection ranging from 0.130 inch to 0.105 inch under a load of 100 kilograms. A mantle layer is disposed over the core and a cover is disposed over the mantle.

A golf ball comprising a core composed of a fully neutralized polymer material is disclosed herein. The golf ball also preferably has multiple mantle layers and a cover.

The present disclosure provides a wireless signal transmitting ball to be used in practice or gameplay of a sport and/or other entertainment activities. The ball of the disclosure comprises a microprocessor unit configured to record, process, and transmit data to a paired device. Further disclosed is a method of actuating the ball between different modes. The ball could be used by players during practice to record data about their performance. The ball could also be used by players or game officials or referees to keep score, adjudicate and decide the gameplay. For example, the information about location of the ball could be used to track balls that could potentially be lost. Additionally, data about spin, trajectory, speed, force applied and the like could be used by players or broadcasters for gaining insights to add to viewing pleasure.

A polyurethane coating for a golf ball that is based on polyol mixture containing acrylic polyol and BEPD based caprolcatone polyol is disclosed herein. The polyurethane coating comprises a part A component and a part B component, with the part A component comprising an acrylic polyol, a BEPD polyol, a 3-Oxazolidineethanol, a fluorosurfactant, a hindered amine light stabilizer, a UV-absorber, an optical brightener, a dibutyltin dilaurate catalyst, and an organic solvent, and the part B component comprising an aliphatic polyisocyanate and an organic solvent.

A golf ball with a core comprising polybutadiene and graphene with an embedded IC is disclosed herein. The golf ball preferably has a single core comprising polybutadiene and graphene. Alternatively, the golf ball has a dual core with an inner core comprising polybutadiene and graphene. Alternatively, the golf ball has a dual core with an outer core comprising polybutadiene and graphene.

A golf ball with improved durability is disclosed herein. The golf ball has a mantle layer comprising a blend of ionomers and methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 5 to 15 weight percent of the mantle layer.

A golf ball with a center core comprising polybutadiene and a clay material in an amount ranging from 0.4 to 2.5 weight percent of the center core is disclosed herein. Alternatively, the golf ball has a mantle layer with a blend of ionomer materials and a clay material in an amount ranging from 0.4 to 2.5 weight percent of the mantle layer.

Provided is a bismuth golf ball with improved carry distance and fracture strength by adding a nano bismuth reformed by using plasma or a nano bismuth alloy manufactured by using the nano bismuth to a resin composition as a base material as compared with a bismuth golf ball in the related art. Since the nano bismuth golf ball has a more densified internal structure due to a higher content of bismuth as compared with the bismuth golf ball, the resilient elasticity is improved, and thus, the carry distance is increased.

Golf balls comprising a multi-layer core and a cover are disclosed. The multi-layer core comprises a center, an intermediate core layer, and an outer core layer. At least one layer of the multi-layer core is a high specific gravity layer.
