| Abstract: | In this paper, EPDM/PP blends with different rubber plastic ratio are extruded separately in dynamic and steady condition from the tri-screw dynamic mixing extruder, and the tensile strength of samples are investigated in the experiment. The results show that the tensile strength of EPDM/PP blends are enhanced after the vibration frequency and amplitude are introduced to the experiment. The law of vibration force field influencing EPDM/PP blends and the effects are analyzed. |
