The Golf Ball Guide: Golf Ball Construction

GOLF BALLS CONSIST OF A CORE, in some cases layering, and always a cover with dimples.

Often made of rubber, the core determines compression rating, which is expressed as a number such as 74, 88, or 105. (A denser core has higher compression.) The higher the number, the more force that’s required to compress (squash) the golf ball at impact. As a result, high-compression golf balls are normally used by golfers with faster swing speeds. Lower-compression golf balls are preferable for golfers with slower swing speeds, making it easier to compress the ball and generate more distance.

Located between the core and the cover, layers (found in multi-piece golf balls) add playability features such as spin, distance control and accuracy.

Golf ball covers are made of ionomer (a polymer material containing ion) or urethane (a synthetic compound). Created by Dupont and known for its durability, Surlyn® has been a popular ionomer golf ball cover for a half century. Urethane covers are used in premium golf balls and are often favored by golfers who value softer feel and more spin.

The dimples on golf balls help create flight. Varying in shape and pattern—and usually numbering 300 and up per golf ball—dimples affect spin rate, distance and accuracy.

Put simply, think of the core as the engine of the golf ball and the dimples as the wings, as a Titleist senior project manager explained.
