ABSTRACT:
A golf ball comprising a core having a first density formed from a diene rubber composition including glass microspheres having an isotactic crush strength of about 5,000 psi or greater and having a true density of about 0.70 g/cm3or less, the microspheres being present in an amount sufficient to lower the first density to about 1.05 g/cm3or less; a cover; and an intermediate layer disposed between the core and the cover, the intermediate layer having a density of from about 1.3 g/cm3to about 1.9 g/cm3and including a composition formed from a compatibilized blend of a non-ionic fluoropolymer and an acrylate-based polymer; wherein a ratio of the core density to the intermediate layer density is between about 0.81 to about 0.5.
