Abstract:In this study, thermoplastic vulcanisates (TPVs) based on ethylene vinyl acetate copolymer (EVA)/styrene butadiene rubber (SBR) blends were prepared by dynamic vulcanisation. The increase in EVA content in blends contributes to the increase in tearing strength and hardness properties, while tensile strength and elongation at break reach a maximum at 40 wt-% of EVA content. The stress-strain curves of EVA/SBR TPVs show obvious elastomer behaviour. The morphological study of the fracture surface of EVA/SBR TPVs reveals the quite smooth surface, which was caused by the strong recovery effect of vulcanised SBR. The phase structure shows that the SBR vulcanisate particles are dispersed finely in TPVs.
