Silicone rubber (VMQ) is a rubber with Si-O bond as a backbone and has superior mechanical properties and heat resistance at high temperatures than organic synthetic rubber. On the other side, Fluorosilicone rubber (FVMQ) is an elastomer that has siloxane backbone and flourocarbon functional groups. So it has excellent oil resistance and mechanical properties. However the high price of FVMQ limits the more active application of FVMQ, we decided to use blends of VMQ and FVMQ. In this study, VMQ/FVMQ blends were evaluated with the effects of compatibility and compression set. The compression set effects were investigated with long-term heat aging (70h, 250h, 500h, 1000h). Also we confirmed that the compatibility of the blends were significantly affected by the ratio of the VMQ/FVMQ. In addition, we investigated the effects of silica as a compatibilizer on VMQ/FVMQ blends.
