Abstract: |
EPDM/Poly(1-butene)(PB) thermoplastic vulcanizate(TPV)was prepared by dynamic vulcanization.The properties of the TPV and reprocessed TPV with different blending ratio of rubber and plastic were investigated.The results showed that,with the decrease of EPDM/PB blending ratio,the Shore A hardness,tensile strength and tear strength of the TPV increased.When EPDM/PB blending ratio was 60/40,the elongation at break and thermo-oxidative aging property of the TPV were the best.Within the scope of the experiment,when EPDM/PB blending ratio was 70/30,the properties of reprocessed TPV was the best. |
