Black
Description
Available in homopolymer (CO), copolymer (ECO), and terpolymer (GECO) formats, Epichlorohydrins are oil resistant compounds.
Key Uses
Ideal for fuel and air conditioning system components. Used in the petroleum industry where a higher temperature capability than NBR is required.
Temperature Range
Standard Compound: -40°F to 275°F
Hardness (Shore A)
50 to 90
Features
Epichlorohydrin features excellent resistance to hydrocarbon oils and fuels; low solvent and gas permeability; excellent resistance to ozone and weathering; and stable cycling from low to high temperature. Good replacement to butyl when gas permeability and oil resistance are needed.
Limitations
Compression set is only “fair” at elevated temperatures (250°F to 275°F). Epichlorohydrin is attacked by ketones; esters; aldehydes; chlorinated and nitro hydrocarbons; and is not recommended for exposure to brake fluids.
