Abstract:
A golf ball comprising:a core having a diameter of 1.50 inches to 1.56 inches, the core comprising polybutadiene, zinc oxide in an amount of 7 to 15 parts per hundred parts of polybutadiene, zinc diacryalate in an amount of 20 to 50 parts per hundred parts of polybutadiene; an initiator in an amount of 0.1 to 1.0 parts per hundred parts of polybutadiene, and tungsten in an amount of 5 to 10 parts per hundred parts of polybutadiene, the core having a PGA compression of 60 to 80 points; and a cover having a thickness of 0.060 inch to 0.090 inch, the cover comprising an ionomer blend formed from a high acid ionomer resin neutralized with zinc in a range of 20 to 40 weight percent of the ionomer blend, and a terpolymer neutralized with magnesium in a range of 80 to 60 weight percent of the ionomer blend, and a Shore D hardness ranging from 52 to 58 as measured on the golf ball; wherein the golf ball has a PGA compression ranging from 80 to 95 points and a COR at 143 feet per second of 78.2 to 80.5, and the golf ball has a lattice structure aerodynamic pattern.
