Golf Ball

At least 50 million people the world over play golf. There are more than 500,000 players in Germany alone, and their numbers are steadily increasing. It therefore comes as no surprise that this sport has created its own industry, which produces around one billion golf balls per year worldwide.

Although the balls all look pretty much the same on the outside, they are not in fact identical. A glance beneath the exterior reveals major differences. The hard balls, which may not weigh more than 45.93 grams and must have a diameter of at least 42.67 millimeters, are sophisticated pieces of sports technology with highly developed specific properties. For many years now, scientists have been investigating the balls’ cover, core, and dimples. The golf balls’ core is made of synthetic rubber supplied by our company.

A golf ball needs to have good playing properties. In order for the ball to fly several hundred meters and land where the player wants it to, as little energy as possible should be lost when the golf club strikes the ball. This is where rubber comes into play. With it in the core, the ball flies farther than is the case with conventional rubber. The BUNA® CB Butadiene Rubber used in the cores of high-quality balls has very good rebound elasticity.

This characteristic is of crucial importance to rubber items, since it is an indicator of how economically an elastomer uses energy when it undergoes deformation. A good rebound elasticity means that a rubber item releases most of the mechanical energy put into it without being transformed into heat when it returns to its original shape after being subjected to a load.
