Combination of sticky surface top sheet with extremely hard sponge has been a key weapon for China to dominate the modern table tennis world.

​

 But the uncomfortable truth is that unhealthy external chemicals like speed glue should be applied to balance out the proper elasticity from these hard rubbers.

 Boosters are not only illegal in ITTF but also extremely impractical to use. Boosters also often increases the thickness of rubber over the rule of 4mm. Solution is New Technology. World-renowned TENSOR BIOS technology softens the hard rubber without illegal external substances to reach the proper elasticity in hard rubber.
