Selecting the material is the most critical decision for B2B buyers. TPE (Thermoplastic Elastomer) is the most popular choice for mid-range markets due to its eco-friendly properties, light weight, and excellent cushioning. For the premium or professional segment, Natural Rubber combined with a PU (Polyurethane) top layer is preferred because it offers superior non-slip grip even when wet and high durability. PVC remains an option for budget-conscious bulk orders, but you must ensure it is 6P free (phthalate-free) to meet safety standards.
