What are the fluoroelastomer examples suitable for high - temperature environments?

Fluoroelastomers are a class of synthetic rubber materials known for their exceptional resistance to heat, chemicals, and oils. These properties make them highly suitable for applications in high-temperature environments, where traditional elastomers would quickly degrade. As a leading supplier of fluoroelastomers, I have extensive experience in providing high-quality products that meet the demanding requirements of various industries. In this blog post, I will introduce some of the most suitable fluoroelastomer examples for high-temperature environments and explain their unique features and applications.

Viton Fluoroelastomers

Viton is a well-known brand of fluoroelastomers produced by Chemours. These fluoroelastomers are based on copolymers of vinylidene fluoride (VDF) and hexafluoropropylene (HFP), with or without tetrafluoroethylene (TFE). Viton fluoroelastomers offer excellent resistance to high temperatures, with continuous service temperatures ranging from -20°C to 200°C, and short-term exposure temperatures up to 230°C. They also exhibit outstanding resistance to a wide range of chemicals, including fuels, oils, solvents, and acids.

One of the key advantages of Viton fluoroelastomers is their high mechanical strength and abrasion resistance. This makes them suitable for applications where the elastomer needs to withstand high pressures and friction, such as seals, gaskets, and O-rings in automotive engines, aerospace systems, and industrial machinery. Viton fluoroelastomers are also used in the chemical processing industry for lining pipes, valves, and pumps to protect against corrosion and chemical attack.

Kalrez Perfluoroelastomers

Kalrez is a brand of perfluoroelastomers manufactured by DuPont. Perfluoroelastomers are the highest performing fluoroelastomers, offering the best resistance to high temperatures, chemicals, and solvents. Kalrez perfluoroelastomers are based on a fully fluorinated polymer structure, which provides exceptional thermal stability and chemical resistance. They can withstand continuous service temperatures up to 327°C, and short-term exposure temperatures up to 343°C.

In addition to their high-temperature resistance, Kalrez perfluoroelastomers also offer excellent compression set resistance, which means they can maintain their sealing properties over a long period of time, even under high pressures and temperatures. This makes them ideal for use in critical sealing applications in the semiconductor, chemical processing, and oil and gas industries. Kalrez perfluoroelastomers are also used in the food and beverage industry, as they are compliant with FDA regulations for food contact applications.

Fluorosilicone Rubber

Fluorosilicone rubber is another type of fluoroelastomer that is suitable for high-temperature environments. It combines the heat resistance and chemical resistance of fluoroelastomers with the flexibility and low-temperature properties of silicone rubber. Fluorosilicone rubber can withstand continuous service temperatures ranging from -55°C to 200°C, and short-term exposure temperatures up to 230°C.

One of the unique features of fluorosilicone rubber is its excellent resistance to fuels, oils, and solvents, as well as its low compression set and good sealing properties. These properties make it suitable for use in automotive, aerospace, and industrial applications, such as seals, gaskets, and O-rings. Fluorosilicone rubber is also available in different forms, such as Transparent Fluorosilicone Rubber, Conductive Fluorosilicone Rubber, and Extruded Fluorosilicone Rubber, which can be tailored to specific application requirements.

Tecnoflon Fluoroelastomers

Tecnoflon is a brand of fluoroelastomers produced by Solvay. These fluoroelastomers are based on copolymers of vinylidene fluoride (VDF) and hexafluoropropylene (HFP), with or without tetrafluoroethylene (TFE). Tecnoflon fluoroelastomers offer excellent resistance to high temperatures, chemicals, and oils, with continuous service temperatures ranging from -20°C to 200°C, and short-term exposure temperatures up to 230°C.

Tecnoflon fluoroelastomers are known for their high mechanical strength, good processability, and excellent resistance to compression set. They are widely used in the automotive, aerospace, and industrial industries for applications such as seals, gaskets, O-rings, and hoses. Tecnoflon fluoroelastomers are also available in different grades and formulations, which can be customized to meet specific application requirements.

Conclusion

In conclusion, fluoroelastomers are an excellent choice for applications in high-temperature environments due to their exceptional resistance to heat, chemicals, and oils. Viton, Kalrez, fluorosilicone rubber, and Tecnoflon are some of the most suitable fluoroelastomer examples for high-temperature applications. Each of these fluoroelastomers has its own unique features and advantages, which make them suitable for different types of applications.
