Abstract
The present invention is directed toward the novel use of thermoplastic materials to form center core shells for use in liquid filled golf balls. Golf balls of the present invention employ liquid filled centers formed from thermoplastic shells, preferably made of a polyether-ester, the shells having a tensile modulus of about 3 ksi to about 10 ksi, preferably a hardness of about 20 to about 80 shore D, preferably a flexural modulus of about 5.5 ksi to about 8.5 ksi, preferably a wound layer, and preferably a specific gravity of greater than 1.5. The shell has a thickness of about 0.005 inches to about 0.5 inches.
