Why Choose D Eleven Tech for FFKM O rings

Perfuoroether rubber (FFKM for short) is a high-performance synthetic rubber made by ternary copolymerization of tetrafluoroethylene (TFE), perfluoromethyl vinyl ether (PMVE) and perfluoroene ether. This rubber material has a unique molecular structure in which all hydrogen atoms on carbon atoms are replaced by fluorine atoms, forming a rubber that does not contain C-H bonds at all. This structure gives perfluoroether rubber extremely high chemical and thermal stability, making it an indispensable high-performance sealing material in modern industry.

The density of perfluoroether rubber is usually between 1.9-2.0g/cm’, and its physical and mechanical properties are close to those of fluororubber, but its high-temperature compression permanent deformation performance is better than that of fluororubber. Its long-term use temperature range can reach -39°C to 288°C, and its short-term use temperature can even reach 400°C. It still has a certain plasticity below the brittle temperature, is hard but not brittle, and can be bent. In addition, perfluoroether rubber also exhibits excellent chemical resistance and can withstand attacks from up to 1,600 chemicals, including strong acids, strong alkalis, organic solvents, corrosive gases, high-temperature superheated water-steam, etc.

Application of perfluoroether rubber seal ring-FFKM seals

• Semiconductor industry: In the semiconductor manufacturing process, FFKM seals are used in various sealing occasions with high cleanliness requirements, such as the exhaust valve seal of the chip anhydrous etching method, the seal of the filter and the electric coupler in the optical masking test, etc. Its excellent resistance to plasma corrosion and gas corrosion ensures the stable operation of semiconductor manufacturing equipment.
• Pharmaceutical industry: In the pharmaceutical process, FFKM seals are used for sealing various corrosive fluids and high-temperature and high-pressure environments. Its non-toxic, odorless, chemical corrosion resistance and biocompatibility ensure the safety and reliability of the pharmaceutical process.
• Petrochemical: In the petrochemical industry, FFKM seals are used for sealing various highly corrosive media and high-temperature and high-pressure environments. It can withstand corrosion from chemical media such as ethers, ketones, esters, alcohols, aldehydes, amines, strong oxidants, etc., ensuring the safe operation of equipment and systems
• Aerospace: In the field of aerospace, FFKM seals are widely used in sealing components of various aircraft and spacecraft due to their light weight, high strength and high and low temperature resistance. It can maintain stable performance in extreme environments to ensure the safe flight of aircraft and spacecraft.
• Other fields: FFKM seals are also widely used in automobile manufacturing, laser electroplating, battery industry, special equipment manufacturing and other fields. In automobile manufacturing, FFKM seals are used for sealing engines and transmission systems; in laser electroplating, FFKM seals are used for sealing vacuum cabins and box covers; in the battery industry, FFKM seals are used for sealing battery housings, etc.

Perfluoroether rubber (FFKM), as a high-performance synthetic rubber material, has excellent chemical resistance, heat resistance, high pressure resistance and wear resistance. As a sealing element made of this material, FFKM seals play a vital role in semiconductors, pharmaceuticals, petrochemicals, aerospace and other fields.
