Abstract
A handgrip, such as a golf club grip, having improved non-slip features is shown which is formed from a silicone rubber composition. The silicone rubber composition comprises an organopolysiloxane gum, a silica filler material, as organosilicone processing aid, a texturizing material, and a quantity of hollow spheres. The texturizing material and spheres are first blended into the composition while heating the composition. The rubber composition is then placed in a suitable mold and cured with a peroxide catalyst to form the handgrip. The external surface of the cured handgrip is buffed to fracture the hollow spheres nearest the surface and improve the non-slip character of the handgrip.
Claims3
A method of forming a handgrip having improved non-slip features, comprising:
- blending a silicone rubber composition from an organopolysiloxane elastomer, a filler material, an organosilicon processing aid, a texturizing material, and a quantity of hollow spheres, the hollow spheres having a density in the range from 0.5 to 0.9 grams/cc;
- heating said rubber composition during the blending step to evenly disperse said texturizing material and said hollow spheres within said rubber composition without reacting said texturizing material with said organopolysiloxane elastomer;
- cooling and curing said composition to form a handgrip the exterior surface of said handgrip being formed to contain exposed portions of said hollow spheres which are blended throughout said silicone rubber composition;
- buffing the exterior surface of said handgrip to fracture the exposed portions of said hollow spheres and thereby present a roughened exterior surface to said handgrip.
