FFKM Preferred material for high demand applications
Jul 27,2023
Perfluoroelastomer (FFKM) refers to a series of high-performance polymer materials, with the advantages that traditional rubber materials can not match, especially in the sealing needs involving high temperature, chemical corrosion, high pressure and other harsh environments, the performance is particularly outstanding.
FFKM has extremely high temperature resistance, which makes it particularly important in the petroleum, chemical and other industries. Conventional sealing materials can rapidly age, harden or lose elasticity in high temperature environments, while FFKM is able to maintain its good physical properties at high temperatures, able to withstand temperatures up to 250°C and beyond. In some special applications, FFKM can even withstand high temperatures above 300°C, which makes it ideal for high-temperature steam, thermochemical reactions and other fields.
FFKM's chemical resistance is almost unmatched. It can resist almost all types of chemicals, including strong acids, strong bases, solvents, oils, and various toxic gases. Many traditional sealing materials will expand, dissolve or deteriorate under the erosion of these chemical media, resulting in seal failure. FFKM can maintain its integrity and elasticity in the face of highly corrosive substances such as chlorine, hydrofluoric acid, sulfuric acid and ammonia. This makes FFKM the material of choice for sealing in highly corrosive environments in the chemical, pharmaceutical, oil and gas and other industries.
FFKM also has excellent mechanical properties and wear resistance to withstand high pressures and dynamic loads, maintaining a stable sealing effect. Whether in gas pipelines, reactors, oil and gas well equipment or various industrial machinery, FFKM can effectively prevent leaks and ensure the normal operation of equipment. In high pressure environments, FFKM performs well, can withstand hundreds of bar pressure without deformation, long-term work will not appear significant aging or performance degradation.
FFKM's low compression permanent deformation and ozone resistance enable it to maintain its sealing performance and elasticity even when exposed to ultraviolet light and oxygen for a long time, which makes it suitable for long-term use in harsh environments and reduces the frequency of equipment downtime and maintenance. FFKM's aging resistance guarantees its long life and provides a reliable seal even under harsh operating conditions.
FFKM seals It can not only improve the safety and stability of the equipment, but also effectively reduce maintenance costs and downtime, becoming the ideal material to meet the demanding sealing requirements.
