Introduction
Full PU System Track are outstanding anti-UV, excellent anti-aging property, and wearresistance performance. It is not only meet the IAAF(lnternational Association Of Athletics Federations) sports surface standard requirement such as shock absorbtion, strong tensile strength, force reduction and vertical deformation etc, also it is very environmental protection, Its advantage is made from 100% MDI, this synthetic running track material system is odorless and free-solvent, it is comfortable and safe,and its service life is more than 15 year.
