What are the different types of fluororubber for gasket?
As a supplier of fluororubber for gaskets, I've witnessed firsthand the diverse applications and unique properties of different types of fluororubber. In this blog, I'll delve into the various types of fluororubber suitable for gaskets, highlighting their characteristics, applications, and advantages.
1. Standard Fluororubber (FKM)
Standard fluororubber, commonly known as FKM, is one of the most widely used types for gaskets. It offers excellent resistance to high temperatures, oils, fuels, and chemicals. FKM can withstand temperatures ranging from -20°C to 200°C, making it suitable for a variety of industrial applications.
The chemical structure of FKM contains fluorine atoms, which provide exceptional resistance to swelling and degradation when exposed to aggressive media. This makes it an ideal choice for gaskets in automotive engines, oil and gas pipelines, and chemical processing plants.
One of the key advantages of FKM is its durability. Gaskets made from FKM can maintain their sealing properties over long periods, even under harsh operating conditions. They are also resistant to ozone and weathering, ensuring reliable performance in outdoor environments.
2. Perfluoroelastomer (FFKM)
Perfluoroelastomer, or FFKM, is a high-performance fluororubber that offers superior chemical resistance compared to FKM. FFKM can withstand exposure to a wide range of aggressive chemicals, including strong acids, bases, and solvents. It also has excellent thermal stability, with a continuous service temperature of up to 327°C.
Due to its exceptional chemical and thermal resistance, FFKM is commonly used in critical sealing applications where reliability is paramount. It is often found in the semiconductor industry, pharmaceutical manufacturing, and aerospace applications. Gaskets made from FFKM can provide a tight seal in environments where other materials would fail.
Another advantage of FFKM is its low compression set. Compression set refers to the ability of a material to recover its original shape after being compressed. Gaskets with low compression set can maintain their sealing force over time, ensuring a reliable seal.
3. Tetrafluoroethylene - Propylene (FEPM)
Tetrafluoroethylene - propylene, or FEPM, is a fluororubber that combines the excellent chemical resistance of fluoropolymers with the elastomeric properties of rubber. FEPM has good resistance to acids, bases, and steam, making it suitable for applications in the chemical, food, and beverage industries.
One of the unique features of FEPM is its resistance to amines. Amines are a class of chemicals that can cause degradation in some types of rubber. Gaskets made from FEPM can provide a reliable seal in applications where amines are present, such as in the automotive and oil and gas industries.
FEPM also has good mechanical properties, including high tensile strength and tear resistance. This makes it suitable for use in gaskets that require high durability and reliability.
4. Fluororubber for Oil Seal
If you're specifically looking for fluororubber for oil seals, you can find more information on our website Fluororubber for Oil Seal. Oil seals made from fluororubber offer excellent resistance to oil and grease, as well as good mechanical properties. They can prevent leakage of lubricants and contaminants, ensuring the proper functioning of machinery.
5. Fluororubber for O - rings
O - rings are a common type of gasket used in a variety of applications. Fluororubber for O - rings provides excellent sealing performance and resistance to a wide range of chemicals and temperatures. You can learn more about our Fluororubber for O - rings on our website. O - rings made from fluororubber can be used in hydraulic systems, pneumatic systems, and other applications where a reliable seal is required.
6. Food Grade Fluororubber
In applications where food contact is involved, such as in the food and beverage industry or pharmaceutical manufacturing, food grade fluororubber is essential. Our Food Grade Fluororubber meets strict regulatory requirements and is safe for use in contact with food and beverages. It offers the same excellent chemical and thermal resistance as other fluororubbers, while also being compliant with food safety standards.
Choosing the Right Fluororubber for Your Gasket Application
When choosing the right fluororubber for your gasket application, several factors need to be considered. These include the chemical compatibility of the material with the media it will be exposed to, the operating temperature and pressure, the mechanical properties required, and any regulatory requirements.
For general industrial applications, standard FKM is often a good choice due to its excellent balance of properties and cost - effectiveness. However, for critical applications where high chemical or thermal resistance is required, FFKM or FEPM may be more suitable.
