The data in this article aims to accurately describe the evolution of the network structures and physical mechanical properties of rubber composites during annealing process. Tensile stress-strain curves of un-vulcanized rubber gums and compounds were obtained by an electrical tensile tester with a speed of 100 mm/min. The crosslinking characteristics of the un-vulcanized rubber blends or composites after different annealing time were measured by a rotor-free vulcameter at 150 °C. The macroscopic filler dispersion of the filled vulcanizates was aData in brief104660https://www.ebi.ac.uk/biostudies/studies/S-EPMC6833471biostudies-literatureData on the evolution of curing characteristics and properties during the room-temperature annealing process in SSBR/BR gums and SSBR/BR/SiO2 composites.PMC6833471Wang CZhang XCai LHe AfalseData on the evolution of curing characteristics and properties during the room-temperature annealing process in SSBR/BR gums and SSBR/BR/SiO2 composites.The present article contains the data of tensile stress-strain curves, crosslinking characteristics curves, filler dispersion images and dynamic mechanical properties of SSBR/BR blends and SSBR/BR/SiO2 composites during room-temperature annealing.
