Epichlorohydrin rubber (ECH / ECO) is a superior grade, multipurpose polymer that’s widely-used in automotive applications. It bridges the gap between nitrile and other considerably more expensive polymers.
Epichlorohydrin rubber (ECH / ECO) offers excellent performance in high and low temperatures. Due to its temperature flexibility, epichlorohydrin rubber (ECH / ECO) has become increasingly popular in severe applications like arctic refueling hose assemblies and tubing, and sealing conditions.
Often compared to Nitrile, epichlorohydrin rubber (ECH / ECO) offers better heat, oil and petrol resistance. It’s extensively used in fuel applications such as automotive fuel systems, bladders and die-cut sealing. It exhibits excellent resistance to acids, alkalis and ozone exposure. Typical working temperatures range from -35°C to +125°C.
