摘要:
Disclosed herein is a game ball and method for making the same. The game ball has an ionomeric cover which includes a combination of ionomeric crosslinks and covalent crosslinks. The game ball cover is superior in at least one of cut resistance and scuff resistance to a conventional cover that does not have covalent crosslinks but is otherwise substantially identical in composition. The game ball cover of the invention is particularly useful for improving the durability of golf balls to be struck with sharp-grooved clubs.

Disclosed herein is a golf ball utilizing a core that comprises at least two particular types of polybutadiene. In one aspect, a combination of a polybutadiene obtained from a cobalt catalyst is used in conjunction with a polybutadiene obtained from a neodymium catalyst. Also disclosed are golf balls comprising particular cover compositions. In one aspect, a cover composition is disclosed that includes a sodium ionomer, a magnesium ionomer, and a zinc ionomer. The golf balls exhibit improved distance while providing a soft sound and feel.
摘要:
A golf ball includes a lattice reinforced layer, which is a layer made of at least two materials with different properties. The materials are interlocked with each other, where one material forms a grid with pores while the other material protrudes through the pores. In some embodiments, the lattice reinforced layer is manufactured using a shutoff molding technique so that the entire lattice reinforced layer is molded in the same mold. The lattice layer is provided to alter the properties of a layer, such as increasing the durability, toughness, or strength of the layer.
摘要:
A golf ball includes a core made from a highly neutralized polymer that has been mixed with a hardness modifier. The modifier may be a process oil or a plasticizer. In particular, the modifier may be a naphthenic process oil, a paraffinic process oil, a phthalate plasticizer, a trimellitate plasticizer, an adipate plasticizer, a sebacate-based plasticizer, a maleate-based plasticizer, and blends thereof. Also disclosed is a method for manufacturing a golf ball that includes changing the hardness of a highly neutralized polymer core.

摘要:
An over-indexed, optionally cross-linked thermoplastic polyurethane elastomer. Also, the method of making the elastomer, and articles, including golf balls, comprising the elastomer.
摘要:
A method of toughening thermoplastic polyurethane (TPU). The TPU is dipped into a urethane solution having a penetrating agent, then heated and dried for a period sufficient to toughen the surface. Also, articles such as golf balls having a toughened thermoplastic polyurethane surface. The toughened thermoplastic polyurethane surface is more scuff-resistant and has a greater strain-rate shear resistance than the TPU.
摘要:
A fluid turbine comprises a turbine shroud and an optional ejector shroud. The turbine shroud and/or the ejector shroud are formed from a hard shell and a membrane. The hard shell forms a leading edge, a trailing edge, and an interior surface of the shroud. The membrane forms an exterior surface of the shroud. The resulting construction is lighter than previous turbine shrouds.
