Fluorine rubber O-rings, also known as fluororubber seals, come in various types based on their molecular structure and fluorine content, which directly affect their chemical resistance and low-temperature performance. These materials are renowned for their self-extinguishing properties, making them highly flame-resistant. They also offer excellent airtightness, capable of maintaining vacuum levels as low as 1.33×10â»â· to 1.33×10â»â¸ Pa, which is crucial for high-performance applications. Additionally, fluororubber exhibits strong resistance to ozone, weathering, and aging, making it ideal for long-term use in harsh environments.
Due to its outstanding thermal stability, fluororubber can operate effectively at temperatures up to 250°C, making it widely used in automotive and aerospace industries. It is particularly suitable for sealing engine power output bearings, as well as for stem seals, cylinder liner seals, and clutch seals. Other common applications include air filter seals, fuel pump seals, and fuel hose inner linings, where durability and chemical resistance are essential.
Fluororubber seals are commonly used in electrical appliances, auto parts, hydraulic systems, oil pumps, sanitary fixtures, bearings, antenna waterproofing, and lighters. They are compatible with a wide range of substances, including aliphatic hydrocarbons (such as propane, hexane, mineral oils, and fuels), vegetable and animal oils, silicone oils, greases, fire extinguishing agents, and diluted acid-base salt solutions. Their versatility makes them an excellent choice for applications requiring good electrical insulation, oil resistance, and resistance to non-polar solvents.
Whether in industrial machinery or everyday consumer products, fluororubber O-rings continue to play a critical role due to their exceptional performance under extreme conditions.
