Poly Isocyanate Prepolymer have been used in the manufacture of soles since around 1960. Polyurethane soles have better wear resistance and chemical resistance than other common sole materials, and have low density and good dimensional stability.
At present, among the materials used in the footwear industry, polyurethane elastomers account for 6% to 8% of all materials. Polyols for polyurethane shoes are mainly polyadipate series products. Polyester polyurethane has excellent mechanical properties, tear resistance, tensile and wear resistance are better than polyether polyurethane, which can meet the demanding requirements of sole materials.
