"Effects of shear rate on properties of ethylene-acrylate rubber/ polyvinylidene fluoride thermoplastic vulcanizates "
Ethylene-acrylate rubber (AEM)/polyvinylidene fluoride (PVDF) thermoplastic vulcanizate (TPV) was prepared by dynamic vulcanization, and the effects of rotor shear rate during dynamic vulcanization on the microphase structure and properties of TPV were investigated. The results showed that the highe...

| description | Ethylene-acrylate rubber (AEM)/polyvinylidene fluoride (PVDF) thermoplastic vulcanizate (TPV) was prepared by dynamic vulcanization, and the effects of rotor shear rate during dynamic vulcanization on the microphase structure and properties of TPV were investigated. The results showed that the higher the shear rate of the rotor during the dynamic vulcanization process, the more likely the phase inversion of AEM and PVDF occured, and the microscopic phase structure was more refined, forming a TPV with a “sea-island” structure. With the increase of shear rate of rotor, the tensile strength and elongation at break of TPV increased first and then decreased. When the share rate was 75 r/min, AEM/PVDF TPV had better mechanical properties, the tensile strength reached 14.84 MPa, and the elongation at break was 246%. TPV had better hot oil and hot air resistance.
