Epichlorohydrin Rubber: A Versatile Elastomer for Fuel and Oil Applications

Epichlorohydrin rubber (ECO) is a synthetic rubber that has excellent resistance to fuels, oils, and chemicals. It is widely used in automotive, industrial, and aerospace applications, such as hoses, seals, gaskets, and diaphragms. In this article, we will introduce the properties, advantages, and applications of ECO.

Properties of ECO

ECO is a copolymer of epichlorohydrin and ethylene oxide, or a terpolymer of epichlorohydrin, ethylene oxide, and a third monomer, such as allyl glycidyl ether. ECO has a high molecular weight and a low glass transition temperature, which gives it good low-temperature flexibility and elasticity. ECO also has high tensile strength, tear resistance, and abrasion resistance.

One of the main characteristics of ECO is its outstanding resistance to fuels, oils, and chemicals. ECO can withstand exposure to gasoline, diesel, biodiesel, ethanol, hydraulic fluids, brake fluids, antifreeze, and various solvents. ECO also has good resistance to ozone, weathering, and aging.

Advantages of ECO

ECO has several advantages over other elastomers in fuel and oil applications. Compared to nitrile rubber (NBR), ECO has better low-temperature performance, higher heat resistance, and lower gas permeability. Compared to fluorocarbon rubber (FKM), ECO has lower cost, better compression set, and easier processing. Compared to silicone rubber (VMQ), ECO has higher mechanical strength, better fuel resistance, and lower swelling.

ECO can also be blended with other elastomers to improve its properties or reduce its cost. For example, ECO can be blended with acrylonitrile butadiene rubber (NBR) to increase its oil resistance and hardness; with hydrogenated nitrile rubber (HNBR) to increase its heat resistance and dynamic properties; or with ethylene propylene diene monomer rubber (EPDM) to increase its ozone resistance and electrical insulation.

Applications of ECO

ECO is widely used in fuel and oil applications that require high performance and reliability. Some examples are:

  • Fuel hoses: ECO can withstand the high pressure and temperature of fuel injection systems, as well as the aggressive additives in modern fuels.
  • Oil seals: ECO can prevent leakage of engine oil, transmission oil, power steering fluid, and other lubricants.
  • Gaskets: ECO can seal the joints between metal parts in engines, pumps, valves, and other equipment.
  • Diaphragms: ECO can act as flexible membranes in fuel pumps, regulators, meters, and sensors.
