The polyurethane foam material is used widely in the sports field. However, design of foam materials is complicated because the foam material exhibits hyperelastic and viscoelastic properties, and the foam material is affected by microstructure. The purpose of this study is to investigate effects of material properties of polymer and microscopic structure on the macroscopic mechanical behavior. Uniaxial compression tests for 3 polymers of which density is varied, were conducted
