Abstract
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.
Claims9
A golf ball comprising:
- a core;
- and
- a cover disposed about said core;
- wherein said cover comprises a fast reacting aliphatic-based polyurethane and/or polyarea material, wherein said fast reacting aliphatic-based polyurethane and/or polyurea material has a reaction time of less than two minutes at processing conditions, and wherein said aliphatic-based polyurethane and/or polyurea material comprises the reaction product of an aliphatic diisocyanate prepolymer having an isocyanate group (NCO Group) content ranging from 14.0% to 16.5%, an aliphatic polyol and a catalyst.
A golf ball comprising:
- a core comprising a polybutadiene mixture;
- a boundary layer formed over the core;
- and
- a cover formed over the core, the cover composed of a fast chemical reaction aliphatic polyurethane material formed from reactants comprising 1,6, hexamethylene-diisocyanate and a polytetramethylene ether glycol;
- the reactants having an isocyanate group (NCO Group) content ranging from 14.0% to 16.5%.
A golf ball comprising:
- a core comprising a polybutadiene mixture;
- a boundary layer formed over the core;
- and
- a cover formed over the core, the cover composed of a fast chemical reaction aliphatic polyurethane material formed from reactants comprising a diisocyanate and a polyol blend, wherein the fast chemical reaction aliphatic polyurethane material has an isocyanate group (NCO Group) content ranging from 14.0% to 16.5%, a Shore D hardness ranging from 30 to 60 as measured according to ASTM-D2240, and a thickness ranging from 0.010 inch to 0.044 inch.
A golf ball comprising:
- a core;
- and
- a cover formed over the core, the cover composed of a fast chemical reaction aliphatic polyurethane material formed from reactants comprising a polytetramethylene ether glycol terminated 4,4′-diphenylmethane diisocyanate polyurethane prepolymer having an isocyanate group (NCO Group) content ranging from 14.0% to 16.5% and a curative;
- wherein the cover has an aerodynamic surface geometry thereon.
A golf ball comprising:
- a core comprising a polybutadiene mixture, the core having a diameter ranging from 1.35 inches to 1.64 inches and having a PGA compression ranging from 50 to 90;
- a boundary layer formed over the core, the boundary layer composed of a blend of ionomer materials, the boundary layer having a thickness ranging from 0.020 inch to 0.075 inch, the blend of ionomer materials having a Shore D hardness ranging from 50 to 75 as measured according to ASTM-D2240;
- and
- a cover formed over the boundary layer, the cover composed of a fast chemical reaction aliphatic polyurethane material formed from reactants comprising a polytetramethylene ether glycol terminated 4,4′-diphenylmethane diisocyanate polyurethane prepolymer having an isocyanate group (NCO Group) content ranging from 14.0% to 16.5% and a polyol, wherein the aliphatic polyurethane material has a Shore D hardness ranging from 30 to 60 as measured according to ASTM-D2240, a thickness ranging from 0.015 inch to 0.044 inch, and an aerodynamic surface geometry thereon.
