ECO – Epichlorohydrin Rubber

Epichlorohydrin rubber (ECO) has properties similar to nitrile rubber but with better heat, oil and petrol resistance.

  • Has low gas permeability and better low temperature flexibility than NBR.
  • Its resistance to acids, alkalis and ozone is excellent.
  • However, its poor compression set limits its use as a sealing material and its corrosive effect on metals can increase tooling costs and limit metal bonding applications.
  • Typical uses are in automotive fuel systems, bladders, diaphragms and rollers.
  • Typical working temperature range: -35°C to +125°C
