Application of perfluoroether sealing conditions:
Due to the high cost of raw materials for perfluoroether FFKM rubber, the sealing conditions for using perfluoroether FFKM are usually extremely harsh. Other rubber materials cannot meet the sealing requirements under these harsh conditions, and other rubbers are prone to corrosion, swelling, dissolution, aging and hardening under these harsh conditions, resulting in sealing failure. Perfluoroether FFKM rubber, due to its excellent corrosion resistance and high temperature resistance, meets the sealing requirements of harsh working conditions while increasing the service life of seals and reducing customer maintenance costs.
Typical application conditions of perfluoroether FFKM rubber seals include:
*Semiconductor industry (plasma corrosion, gas corrosion, acid alkali corrosion, high temperature corrosion, high cleanliness requirements for rubber seals)
*Pharmaceutical industry (organic acid corrosion, organic alkali corrosion, organic solvent corrosion, high temperature corrosion)
*Chemical industry (strong acid corrosion, strong alkali corrosion, gas corrosion, organic solvent corrosion, high temperature corrosion)
*Petroleum industry (heavy oil corrosion, hydrogen sulfide corrosion, high sulfide corrosion, organic component corrosion, high temperature corrosion)
*Automotive industry (high temperature oil corrosion, high temperature corrosion)
*Laser electroplating industry (high temperature corrosion, high cleanliness perfluoroether rubber cannot precipitate metal ions)
*Battery industry (acid alkali corrosion, strong active medium corrosion, strong oxidizing medium corrosion, high temperature corrosion)
*Nuclear power thermoelectric industry (high-temperature steam corrosion, ultra-high temperature water corrosion, nuclear radiation corrosion)
