Abstract：Solvent-free polyurethane environmental protection material is the preferred material in basketball production， which not only meets the elastic performance of basketball， but also meets the requirements of energy conservation and environmental protection. In this paper， the application of solvent-free polyurethane materials is explained. The preparation process of solvent-free polyurethane elastomer was investigated by means of semi-prepolymer and prepolymer. The basic properties， mechanical properties and dielectric resistance of solvent-free polyurethane elastomers were analyzed.
