The new Sonic Core series is made with Infinergy®, by BASF – a super elastic material, with the benefit of being very light, the perfect match to meet the demands of the modern day player.

Infinergy® foam developed by BASF, the world’s first E-TPU, has significantly higher rebound properties to other materials such as EPP, EVA and EPE. Material rebound tests show a 46% increase in rebound height vs original Sonic Core material. When Infinergy® foam is combined with the Sonic Core frame the result is a faster ball speed off the racket for more aggressive shot-making.

Sonic Core made with Infinergy® is located in the 2 and 10 o’clock areas of the racket, dampening impact shock and reducing frame vibrations by up to 37%,  resulting a more comfortable hitting sensation and a reduced chance of injury.
