The glue used when laying the rubber track is polyurethane glue, which is made of TDI or MDI as raw materials, with polyether and other raw materials in the reactor to react and produce. Polyurethane glue has good adhesion, acid and alkali resistance and corrosion resistance.   The rubber track laid with polyurethane glue has good elasticity, wear resistance, non-slip, beautiful color, and is not affected by the weather. The polyurethane glue is evenly mixed with rubber particles to lay EPDM track or as the bottom layer of permeable spray coat track and sandwich system running track, which is widely used in indoor and outdoor sports fields, decks, swimming pools, kindergartens, greenways, community public recreation areas, etc.
