US 6,290,614 B1 · Golf ball which includes fast-chemical-reaction-produced component and method of making same

Abstract

Disclosed herein is a golf ball comprising one or more fast-chemical-reaction-produced components, such as a component which comprises a reaction injection molded polyurethane material. A process of making a golf ball by forming at least one core and/or cover component of the ball by mixing two or more reactants that react and form a reaction product with a flex modulus of 1 to 310 kpsi, with a setting time of about 30 seconds or less, the component having a thickness of at least 0.01 inches and a mold release time of 2 minutes or less is also disclosed. In one preferred form of the invention, excess polyurethane from forming golf ball covers is recycled by using it to form golf ball cores.

A method of producing a golf ball having a cover including a polyurethane, said method comprising:

providing a first reactant which is an isocyanate;
providing a second reactant selected from the group consisting of a polyol, a polyamine, and combinations thereof;
heating said first reactant to a temperature of from about 90° F. to about 150° F.;
heating said second reactant to a temperature of from about 90° F. to about 150° F.;
mixing said first reactant and said second reactant together;
providing a molding assembly defining a molding cavity and having a golf ball component positioned within said molding cavity;
introducing said first reactant and said second reactant into said molding cavity;
and
forming a cover layer about said golf ball component from said first reactant and said second reactant, thereby producing said golf ball.
