Golf products produced by a stoichiometrically imbalanced RIM system
Disclosed herein are golf products, such as golf balls and/or components thereof, including the product of a fast-chemical-reaction mixture comprising a polyol and an isocyanate. The component is formed by reaction injection molding the reaction mixture. In the reaction mixture, the stoichiometry of the reactants is imbalanced.
1. A golf ball component including the product of a fast-chemical-reaction mixture comprising an isocyanate and a polyol, wherein the mixture has a stoichiometry of from about 50 to about 90 that is imbalanced, and wherein a nitrogen-carbon-oxygen group content of the mixture is greater than a hydroxyl content of the mixture.
2. The golf ball component of claim 1 , wherein the mixture has a stoichiometry of from about 60 to about 90.
3. The golf ball component of claim 2 , wherein the mixture has a stoichiometry of from about 70 to about 85.
4. The golf ball component of claim 1 , wherein the golf ball component has a Shore B hardness of 50 or more.
5. The golf ball component of claim 4 , wherein the golf ball component has a Shore B hardness of from about 80 to about 95.
6. The golf ball component of claim 1 , wherein the component is selected from the group consisting of a one-piece golf ball, a cover, an intermediate layer, a layer of a cover, a core, and a layer of a core.
7. The golf ball component of claim 1 , wherein the polyol comprises hydroxyl functional components and/or amino functional components.
8. The golf ball component of claim 7 , wherein the polyol is a polyether polyol, a polyester polyol, or a polybutadiene.
