Abstract
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.
Claims8
A method for making a golf ball component, the method comprising:
- forming a fast-chemical-reaction mixture comprising an aliphatic isocyanate and a polyol, wherein the mixture has a stoichiometry of from about 50 to about 90 that is imbalanced and has a nitrogen-carbon-oxygen group content of the mixture is greater than a hydroxyl content of the mixture;
- and
- molding the reaction mixture to form a golf ball component in a reaction time of two minutes or less.
