Publication number: 20240149116Abstract: Compositions including a hardness agent and a water releasing agent and golf ball cores made from such compositions having a tailored hardness gradient are disclosed. The type and concentration of the components in the composition, including a hardness agent and a water releasing agent, affect the hardness, hardness gradient, and compression of cores made from the composition and, thus, can be used to produce a golf ball having desirable performance characteristics.Type: ApplicationFiled: September 25, 2023Publication date: May 9, 2024Applicant: Acushnet CompanyInventors: Michael Michalewich, Erin McDermott, Manjari Kuntimaddi, Doug Goguen, Dennis Britton

Patent number: 11944874Abstract: Golf balls having cores with increased hardness gradients are provided. The cores have an increased “positive” hardness gradient (or a “hard-to-soft” hardness) where the outer surface of the core is harder than the center. The increased positive hardness gradient can be achieved by introducing a water-releasing agent into the core rubber formulation during the curing process. The resulting golf balls have reduced spin and sufficient impact durability.Type: GrantFiled: June 14, 2022Date of Patent: April 2, 2024Assignee: Acushnet CompanyInventors: Erin McDermott, Manjari Kuntimaddi, Dennis Britton
