| Abstract: |
| EPDM/low density polyethylene(LDPE) thermoplastic elastomer(TPE) was prepared in two curing systems by dynamic vulcanization,with ethylene vinyl acetate(EVA) as compatibilizer.The results showed that,as the addition level of EVA increased,the shear viscosity of EPDM/LDPE blend decreased and the flow properties increased.Compared with sulfur vulcanization system,the physical property of EPDM/LDPE TPE cured with peroxide was poor,but the heat resistance was better.The comprehensive properties of EPDM/LDPE TPE were better when the addition level of EVA was 18 phr. |
