applications of viton seals
Fluororubber seals, owing to their exceptional resistance to high temperatures, chemical corrosion and oils, find extensive application across multiple critical industrial sectors. Below are their primary application scenarios and characteristics:
1. Aerospace Sector Fluororubber seals are indispensable components in high-tech fields such as aviation and aerospace. They can operate continuously at 250°C and withstand short-term temperatures up to 300°C, while also possessing excellent electrical insulation properties. They are commonly used in critical areas such as engines and fuel systems.
2. Automotive Industry Within high-temperature, high-pressure automotive components such as engines, transmissions, and valves, fluororubber seals effectively prevent fluid leakage, ensuring system reliability. Specific applications include: Engine systems: Piston seals, valve oil seals Transmission systems: Gearbox and differential seals Braking systems: Brake piston seals,Fuel systems: Fuel pump and injector seals
3. Petrochemical Industry. In oil-laden air environments, fluororubber seals (such as the Copeland structure) deliver outstanding performance, operating continuously for 3,000 hours without leakage at 160°C in oil-laden air conditions, significantly reducing maintenance costs.
4. Industrial Manufacturing and Energy Thermal Power Generation: Enhanced reliability following seal upgrades in instrument air compression systems Chemical Equipment: Resistant to acids, alkalis, and water vapour; e.g., over six months’ service in 30% alkali solution heat exchangers Textile Industry: Bleaching machine seals withstand 120°C hydrogen peroxide corrosion Other Sectors Medical Equipment: High-temperature and chemical corrosion resistance for medical instruments
Electronics and appliances: Insulation materials for low-frequency, low-voltage environments. Fluorocarbon rubber seals, with their exceptional temperature resistance (-60°C to 250°C) and chemical stability, are the preferred sealing solution for high-temperature, high-pressure, and corrosive environments. Material selection must match specific operating conditions (temperature, medium, pressure). For instance, Type 26 fluorocarbon rubber offers the best versatility, while tetrafluoroethylene fluorocarbon rubber provides outstanding cost-effectiveness.
