1、 Composition and StructureSurface layer: High density rubber particles with anti slip and wear-resistant properties.Bottom layer: usually designed with flower particles to increase the stability and slip resistance of the floor mat.2、 Production processGym rubber mats are usually made of high-strength EPDM rubber particles and manufactured through hot pressing technology. This process results in high compression tightness and better adhesion of rubber particles, making them less prone to particle shedding.
