Abstract
Abstract A non-wound three piece golf ball which includes a spherical center, an intermediate mantle of elastomeric material covering the center and a molded cover forming the outside surface of the ball. The golf ball has the performance and feel of a three-piece ball. The golf ball has physical specifications which include diameter, 1.680-1.695 inches; hardness (Shore C) 60-95; and coefficient of restitution 0.695-0.810. The center comprises 90-100 parts by weight cis-1, 4 polybutadiene, 20-35 parts by weight cross linking agent, and 10-30 parts by weight filler. The mantle comprises from 90-100 parts by weight cis-1, 4 polybutadiene, 0-10 parts by weight natural rubber, 35-40 parts by weight cross-linking agent and 1-4 parts by weight filler.
