SANWEI NANO surface optimized technology:

Which makes the surface of traditional sticky rubbers to be more active, elastic and delicate, improving the control and spin effect when hitting the new material 40+ ball, creating looping more easily and offering more error-tolerant rate. Combined with the internal energy cake sponge, it shows a new option that could substitute the energy boosting rubbers, while at the same time enhancing the elasticity and the shot speed, allowing the player to handle the rubber with ease.

SANWEI NANO rubber bonding process:

As traditional rubber-adhesive usually becomes a hard layer after solidification, SANWEI trying to solve this defect by applying exclusive soft-adhesive into the rubber bonding process, so that the adhesive layer between the rubber and the sponge is no longer hard, then creating more efficient power transfer between the rubber surface and the sponge, which greatly reduces energy loss, bringing out higher quality hits and more penetrating feel.
