The fluororubber/silicone rubber blends were prepared by using fluororubber grafted by -methacryloxypropyltrimethoxysliane as a compatibilizer. Fourier transform infrared Spectra revealed that -methacryloxypropyltrimethoxysliane has been grafted onto fluororubber backbone. The effect of the compatibilizer content on curing characteristics, stress—strain behavior, mechanical properties, heat aging properties, and oil resistance was investigated. The results showed that the mechanical properties and oil resistance of the blends were improved with increasing of the compatibilizer up to 11.8 wt%. The compatibility of fluororubber and silicone rubber phase was characterized by dynamic mechanical analysis.
Key Words: fluororubber silicone rubber compatibilization blend -methacryloxypropyltrimethoxysliane.
