- Silicon Oil And Grease, Water and its solvents, Refrigerants,Ammonia & Carbon Dioxide Ozone, Weathering and Aging.
CHLOROSULFONATED POLYETHYLENE (CSM – HYPALON ®)
- CHLORINE in CHLOROSULFONATED POLYETHYLENE imparts resistance to Flame and Mineral Oils and also improves Cold Flexibility
- Temperature : -200C to 1200C
- Oxidising Media, Water, Aging, Grease, Many Acids.
PERFLUORO ELASTOMER (FFKM)
- PERFLUOROELASTOMER (FFKM) exhibits unique resistance even in the harshest environments.It exhibits unbeatable resistance to Acids, Alkalis, Steam, Ketones.
- Temperature : -250C to 3000C
- Aliphatic, Aromatic and Chlorinated Hydrocarbons, Organic And In-Organic Acids, Water, Steam, and Vacuum.
The indicated minimum application temperatures are thought as a general guideline because a seals function at lower temperatures is dependent on the kind of the seal.the general application conditions, and on the kind of the surrounding metal parts the seal is in touch with.The indicated upper-temperature limits may be exceeded, but this reduces the service life.Other materials available on request.
In case of doubt you are always welcome to contact our application engineers.
