Abstract

A thermoplastic multi-layer golf ball has a core center having a shell from about 1-6 mm thick defining an interior space about 12-24 mm in diameter, a core layer at least about 5 mm thick outward from the core center, and a cover. The shell includes a first thermoplastic material with first flexural modulus less than about 15,000 psi. The core layer includes a second thermoplastic material with second flexural modulus up to about 15,000 psi and greater than the first flexural modulus and a specific gravity of at least about 1.5 g/cm. The cover includes a third thermoplastic material with a third flexural modulus that in a first embodiment is up to about 5,000 psi and less than the first flexural modulus and in a second embodiment is least about 40,000 psi.
