Characteristics: Retains elasticity at extremely low temperatures (e.g., below -50°C) without glass transition or brittleness.
Key Materials:
Fluorosilicone rubber (FVMQ): Combines the wide temperature range of silicone rubber with the oil resistance of fluorocarbon rubber, making it ideal for low-temperature oily environments. Ethylene propylene diene monomer rubber (EPDM): Exhibits good low-temperature resistance (approximately -50°C), withstands steam and polar solvents, but is not oil-resistant. Applications: Liquefied natural gas (LNG) equipment, spacecraft cryogenic propellant systems, hydraulic equipment in cold regions.
