Custom Perfluoroether O-ring Corrosion Resistant Acid and High temperature resistance 320 ℃ FFKM Rubber

Short Description:

Perfluoroether rubber is a preferred sealing material for high-end manufacturing and extreme working conditions. Its high performance makes it perform well in demanding applications. FFKM has excellent temperature adaptability (-10℃ to 320℃) and unparalleled chemical resistance. It can resist corrosion from more than 1,600 chemical substances such as strong acids, strong alkalis, organic solvents, ultra-high temperature steam, ethers, ketones, coolants, nitrogen-containing compounds, hydrocarbons, alcohols, aldehydes, furans, and amino compounds. It also has excellent resistance to gas and liquid permeation, weather resistance, ozone resistance, and self-extinguishing properties, ensuring safety and reliability under extreme conditions. Its high density and good mechanical properties further enhance the sealing effect and are suitable for scenes with explosive decompression, CIP, SIP and FDA requirements.

Application scenarios
Chemical and petrochemical industries: used for reactors, pumps and valves, resistant to highly corrosive chemicals.
Semiconductor industry: high purity and chemical resistance make it ideal for etching and cleaning processes.
Oil and gas industry: used for well seals and valves, adapting to extreme chemical and thermal conditions.
Electronics Industry: Meet the requirements of high-performance electronic products for chemical resistance and thermal stability.
Fuel Cells: Used for battery pack sealing to ensure no leakage and improve efficiency.

    Detail

    The main advantage of FFKM(Kalrez) is that it has both the elasticity and sealing properties of an elastomer and the chemical resistance and thermal stability of ptfe.  FFKM(Kalrez) produces small amounts of gas in vacuum and exhibits high resistance to a variety of chemicals such as ethers, ketones, amines, oxidants, and many other chemicals.  FFKM(Kalrez) retains rubber properties even when exposed to corrosive fluids at high temperatures.  Therefore, FFKM(Kalrez) is widely used in semiconductor manufacturing, chemical transportation, nuclear industry, aircraft and energy and other industrial fields.
