Sulfur-less EPDM Foam Sealing Material NITTO EPTSEALER™ EH-2200 Series

A sulfur-less, flexible sealing material made of EPDM foam, which prevents metal corrosion.

This is a flexible sealing material made of EPDM rubber that is foamed into a semi-closed cell structure. It is a clean foam that contains no sulfur, which is commonly used in rubber vulcanization and could corrode metals. It can be used for shock absorbing, soundproofing, and dustproofing applications around airtight electronic devices without corroding the metal.



  • Sulfur-less foam exhibits superior metal corrosion resistance.
  • Can be compressed effortlessly and adheres well to uneven surfaces, providing excellent air-tightness and sound insulation.
  • Superior durability, weatherability, heat resistance, and chemical resistance.
  • The foam layer is certified as UL-94HBF flame retardant.(Certified thickness follows the UL Yellow Card.)
