Fluorocarbon is a popular material used in the construction of O-rings. As the name suggests, it’s an organic compound consisting primarily of fluorine and carbon. Depending on the specific type, it may contain other elements like chlorine and hydrogen. Fluorocarbon, however, is characterized by a high concentration of fluorine and carbon. So, what are the benefits of fluorocarbon O-rings?
Heat and Cold Resistance
Fluorocarbon O-rings perform exceptionally well under a wide range of temperatures. They can handle extreme cold and heat without breaking down. A typical fluorocarbon O-ring, for instance, has a temperature range of minus 450 degrees to 500 degrees Fahrenheit. With such a high maximum temperature, they are commonly used in engine bays, commercial ovens, hydraulic systems and other heat-producing equipment.
Chemical Resistance
You can rest assured knowing that fluorocarbon O-rings are resistant to chemicals. They are able to withstand a variety of otherwise aggressive chemicals, including oils, fuels and even mineral acids. Traditional rubber seals will often break down and degrade when exposed to chemicals such as these. And once a rubber seal has been compromised, it will leak. Fluorocarbon O-rings, though, can withstand aggressive chemicals — all while protecting the parts with which they are used from leaks.
Creep Resistance
Another benefit of fluorocarbon O-rings is creep resistance. Creep refers to the gradual and permanent loss of a seal’s elasticity. It’s typically the result of excessive stress and/or heat. Fluorocarbon O-rings can handle both stress and heat, so creep generally isn’t a concern.
Ozone Resistance
It’s also worth mentioning that fluorocarbon O-rings are resistant to Ozone. Ozone is a type of highly reactive oxygen. It has three oxygen molecules, which makes it a very strong oxidizer. When exposed to ozone, traditional rubber seals will begin to oxidize, resulting in cracking or other forms of damage. Fluorocarbon O-rings, however, are very resistant to ozone.
Low Gas Permeability
Fluorocarbon O-rings have a low gas permeability. Gas permeability represents the ease at which gases can pass through a given material. A high gas permeability means gases can easily pass through the material. A low gas permeability, on the other hand, means it’s difficult for gases to pass through the material. With a low gas permeability, fluorocarbon O-rings are commonly used in sealing applications to maintain pressure and prevent leaks.
In Conclusion
Fluorocarbon O-rings offer a compelling combination of durability, resilience and chemical resistance. Their ability to withstand extreme temperatures, resist aggressive chemicals and maintain structural integrity under stress sets them apart from traditional rubber alternatives. With added benefits like ozone resistance and low gas permeability, these O-rings deliver reliable performance across a variety of industries.
