ABSTRACT:
The present invention is directed to a golf ball comprising a dual core component, an inner cover layer and an outer cover layer. The dual core comprises an interior spherical center component formed from a thermoset material, a thermoplastic material, or combinations thereof. The dual core also comprises a core layer disposed about the center component, formed from a thermoset material, a thermoplastic material, or combinations thereof. The one or more polyurethane layers are preferably formed via a reaction injection molding (RIM) technique. The inner cover layer is relatively soft and preferably comprises an ionomer or ionomer blend. The outer cover layer is relatively hard and comprises a hard polyurethane. The resulting multi-layered golf ball of the present invention provides for enhanced distance without sacrificing playability or durability when compared to known multi-layer golf balls.
