AEM

AEM (Ethylene Acrylic Rubber)

Balanced heat, oil, and weather-resistant elastomer for under-hood, hose, and precision industrial components.

Answer-First Summary

  • Temperature Range: -40 C to +175 C, compound-dependent
  • Media Profile: Oil mist, heat aging, weathering, and selected coolant exposure
  • Engineering Role: Balanced durability material for mixed automotive and industrial environments

Good Fit

Best fit when a component sees heat, oil mist, and outdoor aging but does not need premium FKM chemistry.

Typical Application Windows

Heat-aged molded parts

Hose and connector seals

Industrial actuator components
