NANO RUBBERFILL (Nano Rubber Filling Technology) is referred to as N.R.F. It is a unique fiber board making process of the world. This technology is to implant extremely fine nano rubber filling into the gap between fibers with a special process to support the bottom strength required by the D40+ new ball era bottom board. At the same time, the use of NRF technology can effectively maintain the high elasticity of the bottom board, and effectively avoid the phenomenon that the bottom board is beaten and feels weak. After a lot of tests, NRF technology is subdivided into the following standard values, corresponding to the built-in fiber soft core, built-in fine fiber hard core, external fiber soft core, external fiber hard core, RG technology multi-fiber, and comprehensive ratio (generally the comprehensive ratio is used with most fiber structures, and the balance is the strongest).
