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
