EPDM has excellent resistance to environmental aging, heat aging, ozone, chemical media, water and low temperature. It also boasts good electrical insulation and elasticity, as well as outstanding color stability, ensuring that the color of the products remains unchanged for a long time. It consists of a surface EPDM colored rubber layer and a black rubber buffer layer. Various colors can be matched, and different colors or a single color can be paved arbitrarily. It is particularly suitable for kindergartens, meeting the psychological characteristics of young children. Moreover, it can be directly paved on the concrete surface layer, which can save a lot of foundation costs compared with traditional polyurethane runways.
