The polyurethane composite material for sport knee pad was obtained on the basis of the microcellu?lar polyurethane elastomer formula and the slow rebound foam formula. The effects of polyether polyol, the chain extender and isocyanates on the mechanical properties were also discussed. The results showed that the optimum shock?absorbing performance reached 48?42% when the special polyether content was 70 fractions. The impact ab?sorption performance reached the peak 46?51% when the chain extension agent content was 7 fractions. The prob?lem of the cushioning and motion comfort was solved and avoided the joint damage in sports.
