Impuls rubber from Andro has controlled speed with double function! Impuls is manufactured in a modified Tensor formula and is therefore softer with a higher elasticity than traditional rubbers. It absorbs energy when playing passively and releases energy during active playing. Allround players would never have been able to control such a fast rubber before. Now they can. Slice or block or smash, the 30 degree soft sponge provides the right amount of absorption for every speed.
When attacking with spin or smashing, this allround Tensor construction produces power, resulting in higher ball flight velocity while making the balls fly more precise like a vario-rubber.
