摘要:
A golf ball having a core layer, a mantle layer enclosing the core layer, and a cover layer enclosing the mantle layer. At least one of the layers includes a blend of at least two highly neutralized acid polymers having low flexural moduli. The relative proportion of one highly neutralized acid polymer to the other highly neutralized acid polymer is between about 10:90 and about 90:10.
摘要:
A golf ball includes an inner core and an outer core, both made of highly neutralized acid polymers. The inner core does not substantially include any fillers, while the outer core does include fillers. The outer core may include fillers in an amount of from about 17.% to about 30.7% by weight. The filler may be barium sulfate. The core made from the inner core and the outer core may have an unexpectedly higher coefficient of restitution.

摘要:
A golf ball comprises a core 1 composed of a centre 1a and an outer shell 1b, and a cover 2 covering the core 1, wherein the specific gravity of the centre la is in the range of from 0.2 to 1. The golf ball has an excellent flight distance and satisfies the other requirements of golf balls.
摘要:
A golf ball has a relatively light core center. The golf ball may have a thermoplastic core center with diameter about 28-35 mm and flexural modulus under about 15,000 psi; a thermoplastic core layer with flexural modulus ≤ about 15,000 psi and > the core center's flexural modulus; and a cover ≥ about 2 mm thick with specific gravity ≥ about 2 g/cm3 and flexural modulus ≥ about 15,000 psi. Alternatively, the core center has diameter about 21-29 mm, flexural modulus the core center flexural modulus; and the cover is ≥ about 1 mm thick, has specific gravity ≥ about 1.1 g/cm3, and flexural modulus ≥ about 15,000 psi.
