A golf ball comprising layers that have from 0.05% to 70% by weight of a radio-opaque filler, and wherein the concentration of the radio-opaque filler is measurably different in each layer is disclosed herein. The radio-opaque filler is preferably a compound based on barium, bismuth, tungsten, iodine, or reduced iron.

Method and system for utilizing radio-opaque fillers in multiple layers of golf balls

The present invention is a method for forming a golf ball, the method comprising mixing an aqueous polyurethane dispersion with an azridine to form an aqueous polyurethane dispersion/aziridine mixture. Then, adding the aqueous polyurethane dispersion/aziridine mixture to a water tank, to form a PUD/aziridine solution and dipping a polybutadiene core in the PUD/aziridine solution. The PUD/aziridine solution comprises 0.4 percent aziridine, 4 percent aqueous polyurethane dispersion, and 95.6 percent de-ionized water, which forms a dipped polybutadiene core. The dipped polybutadiene core is then dried at room temperature.

Golf ball adhesion promoter

A method of forming a golf ball is disclosed herein. The method includes placing a golf ball precursor product with a thermoplastic polyurethane cover in a solution containing an isocyanate functionality reactive material. The precursor product is then removed from the solution and heated to remove solvent. The precursor product is then placed in an isocyanate solution. The precursor product is then removed and heated to remove solvent to prepare the precursor product for finishing.

Method for treating thermoplastic polyurethane golf ball covers

A method of forming a golf ball is disclosed herein. The method includes placing a golf ball precursor product with a cover comprising a thermoplastic polyurethane material and a dendritic polymer in a solution containing an isocyanate functionality reactive material. The precursor product is then removed and heated to remove solvent to prepare the precursor product for finishing.

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.

Reaction injection material for a golf ball

A golf ball component, such as a golf ball cover layer, formed from a high or increased melt index thermoplastic polyurethane, polyurea or polyurethane/polyurea is disclosed. The cover layer may be relatively thin (i.e., 0.075 or less, preferably 0.050 inches or less, more preferably less than 0.040 inches, even more preferably less than 0.030 inches). In addition, an operation in which the outer cover is exposed to an isocyanate solution is described to improve certain physical properties of the resulting golf ball.

Golf ball

A two-piece golf ball having a reaction injection molded polyurethane cover is disclosed herein. The golf ball has a core with a diameter preferably ranging from 1.610 inches to 1.670 inches, and a cover having a thickness preferably ranging from 0.015 inch to 0.045 inch. The cover also preferably has a plurality of deep apertures extending through the cover.

Disclosed herein is a golf ball comprising fast-chemical-reaction-produced component, such as a component which comprises a reaction injection molded polyurethane material. The golf ball has excellent light stability. Also disclosed is a method making a golf ball by forming a cover component of the ball by mixing two or more reactants that react and form a reaction product with a flex modulus of from about 1 to about 310 kpsi in a reaction time of about 5 minutes or less, the component having a thickness of at least 0.01 inches and a demold time of 10 minutes or less.

Golf ball which includes fast-chemical-reaction-produced component and method of making same

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.

Golf products produced by a stoichiometrically imbalanced rim system

An apparatus and related techniques for making a golf ball with deep dimples are disclosed. The golf ball comprises a core and a cover layer, wherein the cover layer provides deep dimples that extend through the cover layer and/or into a layer or component underneath are disclosed. At least one percent (1%), preferably about five percent (5%), of the dimples of the ball comprise deep dimples. The cover may be a single layer or include multiple layers. If the cover is a multi-layer cover, the dimples extend to or into at least the first inner cover layer, and may extend to or into two or more inner cover layers. If the cover is a single layer, the dimples extend to or into the core. The dimples may be spherical or non-spherical, and the portion of the dimple that extends to or into the next inner layer may be the same or different shape as the outer portion of the dimple.
