Definition - What does Fluoroelastomer mean?

A Fluoroelastomer is a special type of fluorocarbon-based synthetic rubber that has superior resistance and performance in areas with high temperature. This elastomer performs well in extremely corrosive and high-temperature environments; however, it should meet specific requirements so as to withstand extreme environments. Due to its high resistance to temperature, chemical reaction, corrosion and stress cracking, it is widely used in the chemical industry.

Petropedia explains Fluoroelastomer

As per the American standard of ASTM, fluoroelastomers are commonly abbreviated as FKM. At other parts of the world, they are also abbreviated as FPM or Viton. All the three are same; however, based on the regions and brands, they have been designated different names.

FPM is the international abbreviation as per DIN/ISO standards and the famous rubber manufacturing company Zrunek calls all of its fluoroelastomer materials as FPM whereas, Viton is a trademark name used by DuPont Performance Elastomers.

Such materials possess highly industrial, demand-specific characteristics, such as:

  • Inertness to most chemicals
  • Excellent non-stick
  • Resistance to high temperatures
  • Resistance to galling
  • Abrasion resistance
  • Waterproof
  • Extremely low coefficients of friction
  • Excellent dielectric properties, which are relatively insensitive to temperature and power frequency.
