Abstract
A multilayer golf ball with at least one layer made from an expandable polymeric composition is disclosed comprising a thermally expandable microsphere encapsulating foaming agent wherein the expandable polymeric composition expands from 5% to 200% of its pre-expand thickness when the expandable polymeric composition is exposed to a triggering environmental factor.
Claims8
A multilayer golf ball comprising a core, an intermediate layer, and a cover, wherein the intermediate layer comprises an expandable polymeric composition comprising thermally expandable microspheres encapsulating a foaming agent, said thermally expandable microspheres having an expansion temperature of from about 100° C. to about 180° C., wherein the expandable polymeric composition expands from 5% to 200% of its pre-expand thickness when the expandable polymeric composition is exposed to a triggering environmental factor.
A multilayer golf ball comprising a core, an intermediate layer, and a cover, wherein the intermediate layer comprises an expandable polymeric composition comprising thermally expandable microspheres encapsulating a foaming agent, said thermally expandable microspheres having an expansion temperature of from about 100° C. to about 180° C., the expandable polymeric composition expanding when exposed to a triggering environmental factor to an extent sufficient to comprise an expanded layer having reduced specific gravity.
A multilayer golf ball comprising a core, an intermediate layer, and a cover, wherein the intermediate layer comprises an expandable polymeric composition comprising thermally expandable microspheres encapsulating a foaming agent, said thermally expandable microspheres having an expansion temperature of from about 100° C. to about 180° C., the expandable polymeric composition expanding when exposed to a triggering environmental factor to an extent sufficient to comprise an expanded layer having reduced specific gravity and comprise an impact modification layer to absorb the impact of golf clubs.
