In accordance with the requirements of the prosthetic production process ,we studied the effect of formulation and process conditions on the properties of the rigid polyurethane foam which applied to the manufacture of artificial limbs .The research showed that :when the mass ratio of A ,B component is 1∶1 .45 ,50% compression pressure of the rigid polyurethane foam is 50 .4kg/cm2 ,and the yield pressure up to 28 .3kg/cm2 .Furthermore ,the rigid polyure‐thane foam has good temperature‐resisting and pressure‐resisting and is easy to use ,surface roughness is in line with the requirements of vacuum molding process after repalring .
