    Polyurethane is a polymer with repeating structural units of urethane segments made by the reaction of isocyanate and polyol. Compared with ordinary rubber soles, polyurethane soles have the characteristics of light weight and good wear resistance.

    Polyurethane soles use polyurethane resin as the main raw material, which solves the current domestic plastic soles and recycled rubber soles that are easy to break and the rubber soles are easy to open.

    By adding various additives, the polyurethane sole has been greatly improved in terms of wear resistance, oil resistance, electrical insulation, anti-static and acid and alkali resistance. The author studied the use of new processing technology, molding technology and appearance design, and the safety performance of the shoes is more stable. And it is beautiful and comfortable to wear, durable, reaching the domestic leading level
