It is an emerging organic polymer material, known as the "fifth largest plastic", mostly used in the manufacture of high-end leather shoes, sports shoes, travel shoes and so on. The advantages are low density, soft texture, good elasticity, comfortable and lightweight to wear; good oxidation resistance, excellent wear resistance, flexural resistance, and high hardness; excellent shock absorption and non-slip performance; better temperature resistance; Good chemical resistance; easy to corrode, good for environmental protection, not easy to wrinkle. The disadvantages are strong water absorption, easy yellowing, easy breakage, poor elongation, intolerance to water, perishable bottom, and poor air permeability.
