Can you list fluoroelastomer examples used in automotive seals?

Fluoroelastomers are a class of high-performance polymers known for their exceptional resistance to heat, chemicals, and oils. These properties make them an ideal choice for automotive seals, where they can withstand the harsh conditions under the hood and ensure long-lasting performance. As a leading supplier of fluoroelastomers, we offer a wide range of products suitable for various automotive sealing applications. In this blog post, we'll explore some common fluoroelastomer examples used in automotive seals and their unique benefits.

Viton® Fluoroelastomers

Viton® is a well - known brand of fluoroelastomers produced by Chemours. These fluoroelastomers are highly resistant to a broad spectrum of automotive fluids, including engine oil, transmission fluid, and brake fluid. They can also withstand high temperatures, with some grades capable of operating continuously at temperatures up to 200°C (392°F) and even higher in short - term applications.

In automotive seals, Viton® is commonly used in engine gaskets, shaft seals, and O - rings. For engine gaskets, its chemical resistance ensures that it won't degrade when in contact with hot engine oil and coolant. Shaft seals made from Viton® prevent oil leakage from the engine and transmission, maintaining the proper lubrication of moving parts. O - rings, which are used in various hydraulic and fuel systems, benefit from Viton®'s ability to maintain their shape and sealing properties under high pressure and temperature.

Tecnoflon® Fluoroelastomers

Tecnoflon® is a fluoroelastomer product line from Solvay. It offers excellent resistance to fuels, lubricants, and aggressive chemicals, making it a reliable choice for automotive sealing solutions. Tecnoflon® has good mechanical properties, including high tensile strength and elongation at break, which are important for seals that need to withstand deformation without tearing.

In the automotive industry, Tecnoflon® is often used in fuel system seals. With the increasing use of alternative fuels such as biofuels and ethanol - blended gasoline, Tecnoflon® provides the necessary resistance to prevent fuel leakage and ensure the safety and efficiency of the fuel system. It is also used in turbocharger seals, where it can handle the high - temperature and high - pressure environment generated by the turbocharger.

Fluorosilicone Rubber

Fluorosilicone rubber combines the heat and chemical resistance of fluoroelastomers with the flexibility and low - temperature properties of silicone rubber. This makes it a unique option for automotive seals that require both high - temperature performance and good flexibility at low temperatures.

We offer several types of fluorosilicone rubber products, such as Flame Retardant Fluorosilicone Rubber, Transparent Fluorosilicone Rubber, and High Resilience Fluorosilicone Rubber.

Flame retardant fluorosilicone rubber is suitable for automotive applications where fire safety is a concern, such as in engine compartments and electrical systems. Transparent fluorosilicone rubber can be used in applications where visual inspection of the sealed area is required, for example, in some sensor seals. High - resilience fluorosilicone rubber provides excellent sealing performance even under dynamic conditions, making it ideal for seals in moving parts like pistons and valves.

Perfluoroelastomers (FFKM)

Perfluoroelastomers are the highest - performing fluoroelastomers, offering the ultimate in chemical resistance and temperature stability. They can withstand extreme temperatures up to 327°C (621°F) and are resistant to almost all chemicals, including strong acids, bases, and solvents.

In automotive applications, FFKM is used in high - end seals, such as those in fuel injection systems and high - pressure hydraulic systems. In fuel injection systems, the seals need to be resistant to the aggressive additives in modern fuels, and FFKM provides the necessary protection. In high - pressure hydraulic systems, FFKM seals can maintain their integrity under extreme pressure, preventing fluid leakage and ensuring the proper operation of the system.
