AI Technical Summary

Technical Problem

The existing thermoplastic polyurethane elastomer sole materials have poor elasticity and are prone to permanent deformation, and cannot take into account mechanical properties such as impact strength and tensile strength.

Method used

It adopts highly elastic EVA composite materials, including thermoplastic polyester elastomers, EVA, stearic acid, zinc oxide, zinc stearate, 1,4-cyclohexanediol, magnesium oxide, crosslinked composite materials and AC foaming agents. Through the preparation and molding process of crosslinked composite materials, the material's rebound performance and strength are improved.

Benefits of technology

It significantly improves the rebound performance and comfort of the sole, while ensuring good strength and improving the comprehensive mechanical properties of the material.
