Material Guide: Epichlorohydrin Rubber
Our Guide To ECO – Epichlorohydrin Rubber
Our Epichlorohydrin Rubber (ECO) is a synthetic speciality elastomer produced by combining chloromethyl oxirane and oxirane. This copolymer has very similar properties to nitrile rubber but with superior heat, fuel, oil ozone resistance and improved low-temperature flexibility. These properties work together to make this the perfect elastomer solution for various applications, including automotive fuel systems, air ducts and vibration damping.
What Are The Advantages Of ECO Rubber?
ECO rubber has improved heat, oil and petrol resistance to nitrile rubber, with low gas permeability and superior temperature flexibility. Additionally, ECO rubber is highly resistant to weather conditions and has exceptional heat and mineral oil resistance when compared to Nitrile rubber (NBR). Plus, ECO offers excellent resistance to hydrogen peroxide, ozone and alkalis.
What Are The Disadvantages Of ECO?
ECO rubber has a poor compression set which limits its use as a sealing material. The corrosive effect of ECO on metal materials can increase tooling costs whilst also limiting the number of metal bonding applications this rubber product is suitable for.
What Are The Typical Applications Of Epichlorohydrin Rubber?
ECO rubber is widely used in automotive applications due to its heat resistance and excellent resistance to hydrogen peroxide and mineral oils. These automotive applications can include using ECO rubber for seals, hoses, gaskets, ‘o’-rings, cable jackets and belts. The inherent static dissipative characteristic of ECO makes it ideal for roller covering applications in laser printers and photocopiers.
What Temperatures Can ECO Rubber Operate Under?
ECO has a typical working temperature range of -35°C to +125°C.
