A 3M-company elastomer commonly used in mechanical seal applications with better chemical resistance than either ethylene propylene or Viton ®, but not as good as the super compounds Kalrez® or Chemraz.
Unfortunately the universal rubber or elastomer does not exist, so each time a mechanical seal is specified someone has to select the correct elastomer (O-ring). It might even be you!
