Abstract
A golf ball having a reduced distance while maintaining the appearance of a normal high performance trajectory. The golf ball has a core, an inner cover layer, and a cover. The core has a diameter of from about 1.300 to 1.620 inches, while the ball has a weight from 1.30 to 1.620 ounces, a diameter from 1.670 to 1.800 inches and a maximum Coefficient of Restitution from about 0.600 to about 0.790 as measured at 125 ft/sec incoming ball velocity. The ball has a lift to weight ratio of greater than 1.9 at a Reynolds number of about 230,000 and a spin ratio of about 0.085.
Claims20
A golf ball comprising:
- a core;
- an inner cover layer;
- a cover;
- the core having a diameter of from about 1.300 to 1.620 inches,
- wherein the golf ball has a weight from 1.30 to 1.620 ounces, a diameter from 1.670 to 1.800 inches and a maximum Coefficient of Restitution from about 0.600 to about 0.790 as measured at 125 ft/sec incoming ball velocity and wherein the ball has a lift to weight ratio of greater than 1.9 at a Reynolds number of about 230,000 and a spin ratio of about 0.085.
The golf ball of claim , wherein the core comprises a natural or synthetic base rubber selected from the group consisting of polydienes, polyethylenes (PE), ethylene-propylene copolymers (EP), ethylene-butylene copolymers, polyisoprenes, polyisoprenes, polybutadienes (PBR), polystyrenebutadienes (SBR), polyethylenebutadienes, styrene-propylene-diene rubbers, ethylene-propylene-diene terpolymers (EPDM), fluorinated polymers thereof (e.g., fluorinated EP and fluorinated EPDM), butyl rubber, halogenated butyl rubber, and blends of one or more thereof.
