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.

A canvas holding assembly for holding large and small canvases includes a base that is tripoidal. A first plate is coupled to and extends from the base. The first plate is substantially parallel to a surface upon which the base is positioned and is configured to position items of a user. A first bar is selectively extendable from a top of the base. A second bar is coupled to and extends from the first bar distal from the base. A first coupler is pivotally coupled to the second bar distal from the first bar. The first coupler is positioned above the first plate. Each of a plurality of holders is configured to couple to a canvas. Each holder comprises a second coupler that is complementary to, and positioned to couple to, the first coupler, such that the holder is configured to couple to the canvas.
摘要:
The present invention provides a multilayer film having an active oxygen barrier multilayer core comprising at least one of 1) an active oxygen barrier layer is sandwiched between two passive oxygen barrier layers, or 2) a passive oxygen barrier layer is sandwiched between two active oxygen barrier layers. In one embodiment, the active barrier layer comprises a composition that is a blend of a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, a transition metal salt (B), and an oxygen barrier polymer (C). In some embodiments the active barrier layer may also include a compatibilizer (D). The passive oxygen barrier layers help to maintain the oxygen barrier properties of the multilayer film after the oxygen absorbing capacity of the active barrier layer has been exhausted. As a result, the useful shelf life of the film can be extended.

Disclosed herein is a golf ball having a cover composed of a transparent reaction injection molded polyurethane material. The cover is transparent to visible light and allows for viewing of a core or boundary layer. The core or boundary layer may have a visually appealing color. Further, an indicia may be printed on a surface of the core or boundary layer, and the indicia is visible through the cover material.
摘要:
A golf ball having a spherical shell with a plurality of internal structures is disclosed herein. A fluid material is disposed within the spherical shell. The plurality of internal structures influence the spin decay of the golf ball.
摘要:
Disclosed herein are golf products, such as golf balls and golf clubs, and/or components thereof, including the product of a fast-chemical-reaction mixture comprising a caprolactam polyol and an isocyanate. The component is formed by reaction injection molding the reaction mixture.
摘要:
A golf ball comprises a molded core, one or more ionomer mantles, and a thermoset polyurethane cover. The core is a high cis-polybutadiene crosslinked with zinc diacrylate and may also comprise a halogenated thiophenol and metal thiosulfate. One or more of the ionomer mantles comprises an ionomer neutralized to 80% or greater.
摘要:
Various reaction injection molding (“RIM”) processes and molding equipment are disclosed. In particular, a multi-stage molding process and molding assembly is disclosed for the production of layers or cores on golf balls. The process utilizes a collection of molds, including shuttle molds and/or molding assist members, that readily enables reaction injection molding of layer(s) on golf ball cores or intermediate golf ball assemblies.
