ETPU Machine Manufacturers

The ultra-light and high-rebound ETPU composite shock-absorbing shoe midsole material is prepared from TPU composite material through granulation, foaming and molding processes; the TPU composite material includes, in parts by mass: 60-95 parts of TPU resin, 0 of nylon elastomer resin -20 parts, polyester elastomer resin 0-20 parts, polyester resin 1-5 parts, nucleating agent 0.5-2 parts, antioxidant 0.1-0.5 parts, stearic acid 0.1-1 part and cell stabilizer 0.1-0.5 parts; wherein, the TPU resin is a mixture consisting of TPU resin with a hardness of 90-95A Shore and TPU resin with a hardness of 50-60A, and the proportion of TPU resin with a hardness of 90-95A is 80%- 95%, and the proportion of TPU resin with a hardness of 50‑60A is 5%‑20%. The prepared composite shock-absorbing midsole material has high hardness, high resilience, low compression deformation and high tensile strength while being light in weight, which can greatly reduce the weight of sports shoes , It also has the functions of lasting comfort and lasting shock absorption, giving the wearer a better wearing and running experience.
