"If you think of this inner core as the engine of the golf ball, the inner of the new Chrome Soft is now bigger and softer because it is protected by the stronger outer core, which allows us to pump up the speed, pump up the spin-reducing characteristic of the soft core, and still retain the soft-feel benefits". For years, to get one of those traits, ball manufacturers had to sacrifice the other.
Graphene has reportedly allowed designers to push the limits of compression between the inner and outer core. Callaway believes that with the updated Chrome Soft and Chrome Soft X balls, it has made its best premium ball yet to provide both traits. It's different. Using graphene as a reinforcing agent in the outer core transforms what we can do with performance. In the past when Callaway tried to make the inner core softer and the outer core firmer, the outer core cracked if the difference became too great.
It's 200 times stronger than steel, but is malleable enough to be bent, twisted and folded, and is used on the outer core of the new products, which have a Dual SoftFast core.
Both the 2018 Callaway Chrome Soft balls will go on sale on the 16th of February and both will cost £37.99 per dozen.
"It's a nanoparticle that is extremely strong and extremely flexible", Bartels said of Graphene. It elongates well and stretches well, so it can provide reinforcement for our outer core.
The new Chrome Soft and Chrome Soft X balls continue Callaway's emphasis on lower compression cores for softer feel and less spin off the tee, but they also utilize a softer cover and mantle layer under the cover to produce spin on short game shots. While that sounds an terrible lot like science (and it is, as the discovery of graphene was awarded the Nobel Prize in physics in 2010), what Callaway sees it as is "a game-changer", according to Dave Bartels, Callaway's senior director of golf ball research and development. By using a stronger material, the outer core could be made thinner, which in turn allows for a larger, but still soft, inner core. A soft inner core is made to deform under large impact, and surpresses spin for maximum distance.
Callaway Golf Company, U.S-based maker of golf equipment, unveiled new graphene-enhanced golf balls called Callaway Chrome Soft golf and Chrome Soft X golf balls.
The Chrome Soft is softer than the firmer-feeling Chrome Soft X, which is designed for higher swing speed players (105 miles per hour driver swing speeds and higher) who are looking for less spin on full shots, including not just the driver but the long and middle irons, as well. It is created to appeal to golfers who generate excessive spin off the tee and from the fairway.
