A golf ball that utilizes functional polymers is disclosed herein. The golf ball has at least one of a cover layer or a mantle layer that comprises a first component consisting of a thermoplastic polyurethane or an ionomer, and a second component consisting of a functional polymer in an amount ranging from 0.1 to 80 weight percent of the cover layer or mantle layer.

Golf ball utilizing functional polymers

A golf club head with a cavity at least partially filled with a non-Newtonian shear thinning filler material is disclosed herein. The filler material may comprise multiple materials, such as microbubbles or microbeads, composite polyol materials, blowing agents, and/or graphene to improve performance and dampen sound after the golf club head impacts a golf ball.

Golf club iron comprising shear thinning filler material

A golf ball with improved durability is disclosed herein. The golf ball has a core comprising a polybutadiene material and methyl methacrylate, butadiene, styrene (MBS) with a weight percentage of MBS ranging from 0.5 to 5 weight percent of the core.

Use of an impact modifier in a low compression golf ball

A golf ball with a cover layer composed of at least one polymer and a micropowder material is disclosed herein. The micropowder material comprises polybutadiene rubber, isoprene rubber, zinc diacrylate, zinc oxide, zinc stearate, peroxide initiator, a peptizer, barium sulfate, tungsten, bismuth oxide and or bismuth oxychloride, and styrene butadiene rubber.

X-ray detectable polymers for golf balls

A high elongation golf ball coating is disclosed herein. The coating preferably comprises a one-component polyurethane dispersion (PUD). The coating has an elongation of at least 400 percent. The PUD preferably consists of 20% to 40% weight solids dispersions of polyurethane-filled micelles in a continuous water phase.

High elongation golf ball coating

A golf ball with a cover layer composed of a blend of non- or partially neutralized copolymeric or terpolymeric ionomer(s), hydroxyl-functionalized styrenic block copolymer and silane coupling agent (SCA). The amount of SCA is preferably between 0.01 and 2.0 weight percent based on the total weight of the polymer composition. The cover layer preferably has a Shore A hardness less than 90.

Golf ball cover with silane coupling agent

A golf ball with a cover or mantle layer that comprises a polyurethane and ionomer hybrid made by compounding or dry blending acid functional polyurethane and an ionomer is disclosed herein. The golf ball comprises a core (single core or dual core), a mantle layer (single layer or dual layer) and a cover layer.

Golf ball with an acid-functional polyurethane hybrid

A method for forming a golf ball with a graphene core disclosed herein. The method includes mixing a graphene masterbatch material with a polybutadiene material to form a core mixture, wherein the graphene masterbatch material comprises graphene in an amount from 0.1 to 80.0 weight percent of the graphene masterbatch material mixed with a carrier polymer in an amount from 99.9 to 20 weight percent of the graphene masterbatch material.

Process for incorporating graphene into a core of a golf ball

A method for forming a golf ball core with a nanofiller masterbatch is disclosed herein. The method includes mixing the nanofiller masterbatch, a graphene masterbatch material with other materials to form a core mixture, wherein the masterbatch preferably comprises 1-80% by weight of nanofillers and 20-99% by weight of a carrier polymer.

Process for incorporating nanofiller masterbatch into a core of a golf ball

A golf ball with a core comprising polybutadiene and graphene is disclosed herein. The golf ball has a single core comprising polybutadiene and graphene. Alternatively, the golf ball has a dual core with an inner core comprising polybutadiene and graphene. Alternatively, the golf ball has a dual core with an outer core comprising polybutadiene and graphene.
