FVMQ, a silicone-based rubber, offers excellent chemical resistance. Similar to VMQ, it exhibits superior processability, enhanced low-temperature performance, and exceptional chemical resistance, making it suitable for applications where VMQ falls short. However, due to its high cost, creating a blend that balances cost and mechanical properties is essential. In this study, we used EPDM, a common ethylene-propylene-diene monomer-based material, to fabricate rubber blends. We examined the changes in mechanical properties as the EPDM content increased. This material is intended for use as a sealing material in rocket propulsion systems. Consequently, it must withstand extreme cold, high temperatures, engine oil, and maintain vacuum seal integrity. We evaluated these properties through heat resistance, oil resistance, and compression tests.
