The running track use the mixed structure; the surface is made from EPDM granules and the bottom is made from PU elastic. Since the simple construction technology and the high quality meeting international standards, mixed type running track has been recognized best sports venues internationally.
Character:
Chemical stability EPDM granules could be used for kinds of difficult weather condition, with chemical stability, ozone aging and thermal oxidative aging character. Good elastic EPDM granules could keep the good elastic even under the condition of low temperature. Vivid colors All pigment materials which used for our epdm granules are imported from famous company, colors of epdm granules could keep long time, with strong grey scale and uv stability. Good cohession With many times of experiments and testing, our epdm granules could be mixed with pu binder totally with good cohession. |
