75 Shore A High Temperature Resistant FFKM Kalrez O Ring
75 Shore A High Temperature Resistant FFKM Kalrez O-Ring Rubber Black FFKM Sealing Part By Molding
Description:
Due to the high cost of perfluoroether FFKM rubber raw materials, perfluoroether FFKM sealing conditions
are usually very harsh, other rubber raw materials can not meet the sealing requirements under these harsh
conditions, in these harsh conditions other rubber is prone to corrosion, swelling, dissolution, aging hardening
and other poor, resulting in sealing failure.Due to its excellent corrosion resistance and high temperature resistance,
perfluoroether FFKM rubber can meet the requirements of harsh working conditions, increase the service life of seals,
and reduce the maintenance cost of customers.
Typical application conditions of perfluoroether FFKM rubber seals include:
* Semiconductor industry (plasma corrosion, gas corrosion, acid and alkali corrosion, high temperature corrosion,
rubber seal high cleanliness requirements)
* 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 composition corrosion,
high temperature corrosion)
* Automotive industry (high temperature oil corrosion, high temperature corrosion)
* Laser electroplating industry (high temperature corrosion, high cleanliness of perfluoroether rubber can not precipitate metal ions)
* Battery industry (acid and alkali corrosion, strong active medium corrosion, strong oxidizing medium corrosion, high temperature corrosion)
* Nuclear thermal power industry (high temperature steam corrosion, ultra high temperature warm water corrosion, nuclear radiation corrosion)
