Gray Epichlorohydrin Rubber (ECH / ECO) retains all of the properties of the standard black epichlorohydrin rubber (ECH / ECO), with the exception of its distinguishable light gray color. It’s a cost-effective polymer that bridges the gap between nitrile and considerably more expensive polymers.
Gray epichlorohydrin rubber (ECH / ECO) provides superior strength against tears and resistance. Among its many beneficial properties include good resistance to bio-fuel and abrasion.
Gray Epichlorohydrin rubber (ECH / ECO) has low gas permeability and better low temperature flexibility than Nitrile (NBR). It exhibits excellent resistance to acids, alkalis and ozone exposure. Typical working temperatures range from -35°C to +125°C.
