What is SPU?
Silicon pu (SPU) material is a pavement material for sports venues and facilities, which is made by thermally polymerizing silicone materials and modified materials of polyurethane materials. According to the modified material, the stain resistance, flexibility, wear resistance and recovery rate of the material are improved. In addition, it has excellent cushioning and plasticity, strong adhesion, automatic ground leveling, easy engineering construction, and aging resistance. After the construct in-site, the organic chemical properties are stable, and it is not easy to cause problems such as bubbles.
SPU sports flooring is made by silicon PU / silicon polyurethane materials. It has been implemented for the past 10 years and created a classic name for sports flooring. It is widely used for sports flooring and playground field, especially for outdoor fields.
