Corrosion Index


Corrosion Resistance of selected elastomers

The table below indicates the approximate corrosion resistance of selected elastomers to a range of common chemicals.    This is collated information from various sources but is of limited quality.  For good quality information please consult reputable reference texts and/or the links provided below the table

Key to Letters designating corrosion resistance

  • A...Excellent resistance to corrosion
  • B...Good resistance to corrosion
  • C...Fair resistance to corrosion
  • D...No resistance to corrosion-severe attacke

Important note: The table relates to fluids at ambient temperatures (approx 21o C unless stated otherwise
