Fluorosilicone rubber (FVMQ) is an elastomer composed of siloxane backbone and flouro carbon pendant groups, which has superior oil resistance and mechanical properties. However, FVMQ has problems such as higher price and lower heat resistance than silicone rubber (VMQ). In this study, we investigated change of oil resistance and heat resistance, mechanical properties according to ratio of FVMQ/VMQ. In addition, the properties of FVMQ/VMQ blends were evaluated at long-term heat and oil aging (70h, 250h, 500h, 1000h). In conclusion, we demonstrated that the oil resistance and mechanical properties of the blends were significantly affected by the ratio of the FVMQ/VMQ. The findings of this study can serve as a new roadmap for widening application of FVMQ products.
