Features: Maintains elasticity at extremely low temperatures (below -50°C) without glass transition or brittleness. Key Materials:
Fluorosilicone Rubber (FVMQ): Combines silicone rubber's wide temperature range with fluorocarbon rubber's oil resistance, making it ideal for low-temperature oily environments.
Ethylene Propylene Diene Monomer (EPDM): Excellent low-temperature resistance (around -50°C), resistant to steam and polar solvents, but not oil-resistant.
Applications: LNG equipment, spacecraft cryogenic propellant systems, hydraulic equipment in cold regions.
