While O-rings and sealing components made from other elastomers are prone to failure when exposed to steam, caustic and hazardous media, FFKM (perfluoroelastomer) offers near-universal chemical compatibility.
With superior inert properties, FFKM resists volume swell when exposed to more than 1,800 chemicals, solvents, and plasmas, including:
- Acetic Acid
- Concentrated Nitric Acid
- Sodium Hydroxide
- Ethylene Diamine
FFKM elastomers can withstand the harshest conditions, including those found in medical applications where aggressive agents and/or steam are used for sterilization and semiconductor manufacturing where oxygen plasma is present.
- Excellent chemical resistance (best in class, similar to PTFE)
- Excellent gas and liquid permeation resistance
- Excellent weather ability and ozone resistance
- High Density
- Good mechanical properties, improving sealing performance
The addition of FFKM to the 350 and 370 series iDP family allows engineers to use one valve style in a system that applies both aggressive media and other media.
The proven reliability of FFKM seals in demanding applications may also allow for longer preventative maintenance schedules, resulting in lower costs. At the same time, process throughput, productivity and yields are enhanced from increased equipment uptime.
