Abstract
Golf balls and methods of making same having at least one layer including a microporous composition, wherein the microporous composition includes a polymer component and a filler component and interconnecting pores, so as to improve adhesion between layers, printability of layers, and increase the cure time of the layers and the overall golf ball.
Claims20
A golf ball comprising at least one structural layer formed of a microporous composition comprising:
- at least one polymer component;
- a finely divided particulate filler comprising at least about 50 percent by weight of siliceous particles;
- and
- a network of interconnecting pores communicating substantially throughout the microporous composition,
- wherein the finely divided particulate filler is present in an amount of about 40 percent or greater by weight of the microporous composition.
A golf ball comprising a core and a cover, wherein the cover is formed of a microporous composition comprising:
- a polymer component;
- and
- a finely divided silicate filler present in an amount of about 40 percent or greater by weight of the microporous composition,
- wherein the microporous composition comprises pores comprising about 35 percent or greater of the volume of the microporous composition, and wherein the pores have a volume average diameter of about 0.02 microns to about 50 microns.
A golf ball comprising a structural layer formed of a microporous composition comprising:
- a polymer comprising polyurethane, polyurea, ionomer resin, or mixture thereof;
- a finely divided particulate filler comprising at least about 50 percent by weight of siliceous particles, wherein the finely divided particulate filler is present in an amount of about 40 percent or greater by weight of the microporous composition;
- and
- a network of interconnecting pores communicating substantially throughout the microporous composition.
