Dunlop puts Infinergy in tennis rackets
28/09/2018
Dunlop explained that today’s players tend to use more spin than their predecessors and, as a result, hit the ball more out of the top of the racket than the centre. It said this results in players swinging with more force to generate power and spin, putting extra load on the arm and increasing the likelihood of injury.
By placing BASF’s Infinergy expanded thermoplastic polyurethane (E-TPU) material in key areas of the racket (principally at the positions of two and ten o’clock on a clockface), Dunlop has said it can now offer players strong cushioning, high rebound, speed and lightweight performance.
Tests show a 46% increase in rebound height compared to previous attempts by Dunlop to address this issue and a 2% increase in the ball speed off the racket. Its use of Infinergy has also resulted in a reduction of up to 37% in vibrations compared to a standard carbon fibre racket.
The technology will be included in Dunlop’s new CX racket series, launching in 2019. South Africa’s Kevin Anderson will be one of the first players to use the new rackets.
