Rasanter EC


ENERGY CELL sponge with new highly elastic cell structure for extremely dynamic energy transfer with every ball impulse. The ENERGY CELL sponge generates the highest spin performance of the RASANTER generation.

Energy Cell

With much experience, a cell structure is formed, analyzed and tested until the andro-specific EC cell is born. Clearly visible in the macro image: the colored cell walls of the new sponge. With the same pore size, cell walls with a higher e-module, i.e. higher inner tension, are created.


All sponge variants consist of the special ENERGY CELL material. Each of the three sponges undergoes its own specific thermal treatment - resulting in a specific cell structure for each one of the 3 variants. The ENERGY CELL sponge is the engine for all Rasanter EC rubbers. Each single cell works like a powerful compressor.
The cell properties are multiplied in the entire network and result in the incomparable RASANTER ENERGY CELL performance.
