| Abstract: |
| The influence of blending ratio，PP type，curing system，mixing method and softener level on the properties of EPDM/PP TPE was investigated.The results showed that the tensile strength was greater than 8 MPa，the elongation at break was 400%，the tear strength was 40 kN·m-1，the flex fatigue life was more than 100 kc and the hardness (Shore A)was 70～80 when the EPDM/PP was blended with the ratio of 65/35 and prepared with the one step mixing method；30 phr of softener was suitable. |
