Using ultra-high molecular weight polyethylene (UHMWPE) as the base material,The UHMWPE modified mixture was prepared by adding high-density polyethylene,ethylene-acrylate copolymer,nano SiO2 and other modifiers.According to UHMWPE modified mixture,study has been done about FEP addition and dosage how to effect mechanical properties,wear properties,melt properties and thermal properties of the polymer systems.Results show that before and after FEP added,nanoparticles have good dispersion in the polymer systems;Tensile strength and impact strength as well as thermal properties have little change;Wear properties almost felled 50%,and melt properties improved a little.When FEP was small amount,tensile strength and impact strength of the polymer systems was rising as FEP scales up;when the percentage of FEP is above 2%,tensile strength and impact strength of the polymer systems was falling as FEP scales up.Wear properties of the polymer systems were lowest when the percentage of FEP is 2%.
