Sports floor glue is a type of floor glue specifically developed for sports fields, mainly made of polyvinyl chloride (PVC) material, and added with fillers, plasticizers, stabilizers, coloring agents and other auxiliary materials. It is produced through coating processes or rolling, extrusion or squeezing processes. Sports adhesive is usually composed of multiple layers, including wear-resistant layer, glass fiber layer, elastic foam layer, and base layer. Each layer plays its own role and provides excellent sports performance together.
