Introduction
Sandwich System Synthetic Running Track are outstanding wear-resistance performance. It meets the IAAF(International Association Of Athletics Federations)sports surface standard requirement such as shock absorbtion, strong tensile strength, force reduction and vertical deformation etc, its advantage are soft and elastic, this synthetic running track material is odorless and free-solvent.
