Why AEM Is Superior

AEM is an ASTM-designated elastomer known for exceptional heat and oil resistance. Benefits include:

  • Superior compressive stress relaxation
  • Dynamic fatigue resistance
  • Vibration dampening
  • Acid condensate resistance

Features & Benefits:

  • Best-in-class materials
