Reaction injection material for a golf ball
A golf ball having a layer composed of a polyurethane/polyurea material formed from reaction injection molding a polyol component and an isocyanate component. The polyol component preferably comprises a polytetramethylene ether glycol having a molecular weight of approximately 1000 and a 3,5-diethyl-2,4 toluenediamine. The layer is preferably a cover layer having a thickness ranging from 0.010 inch to 0.025 inch.
1. A golf ball comprising:
a layer comprising a polyol component and an isocyanate component reaction injection molded to form the polyurethane/polyurea material, the polyol component comprising a first polytetramethylene ether glycol having a molecular weight of approximately 1000, a second polytetramethylene ether glycol having a molecular weight of approximately 2000 and a 3,5-diethyl-2,4 toluenediamine, wherein the first polytetramethylene ether glycol comprises 55 to 60 weight percent of the polyol component, the second polytetramethylene ether glycol comprises 15 to 20 weight percent of the poly component, and the 3,5-diethyl-2,4 toluenediamine comprises 15 to 20 weight percent of the polyol component.
