EPDM

EPDM (Ethylene Propylene Rubber)

Weather, ozone, steam, and water-resistant rubber for outdoor, coolant, and energy-infrastructure sealing.

Answer-First Summary

  • Temperature Range: -50 C to +150 C, compound-dependent
  • Media Profile: Water, steam, glycol coolant, ozone, UV, and outdoor weathering
  • Engineering Role: Preferred material when weather resistance matters more than oil resistance

Good Fit

Best fit for long outdoor exposure, water-based media, and enclosure interfaces that need stable compression over time.

Typical Application Windows

Charging enclosure gaskets

BESS cabinet interface seals

Outdoor industrial bellows
