    • Millable polyurethane rubber (MPU) was modified to reduce its friction coefficient by adding ultra-high molecular weight polyethylenes (UHMWPE) and maleic anhydride-grafted polythene (PE-g-MAH). The friction coefficient, surface energy and tensile properties of the blend were influenced by the adding amount of UHMWPE and PE-g-MAH. Compatibility of the blend was analyzed by SEM. The results show that with the increase of adding amount of UHMWPE, the friction coefficient, surface energy and break elongation of the blend reduced, but the elastic modulus increased, and the tensile strength increased at first and then decreased. With the increase of adding amount of PE-g-MAH, the friction coefficient of the blend reduced continuously, the surface energy, tensile strength and break elongation increased at first and then decreased, and the elastic modulus increased. The modified effect of the blend was best in the condition of w(MPU)∶w(PE-g-MAH)∶w(DCP)∶w(UHMWPE)=100∶8∶0.05∶15, and the blend prepared in this condition had the minimum friction coefficient and optimal tensile properties.
