O-Ring Material Selection Guide

  • Standard CompoundSpecial Compound

Rubber compounds are a mixture of polymers, fillers, anti-oxitives and curatives. Various combinations can improve specific properties. Special compounds can be made to broaden temperature range or improve fluid resistance. These may add to lead time, but can lead to better application performance.

Epichlorohydrin

Material Selection Guide

Epichlorohydrin

Trade Names:

  • Hydrin . . . Zeon

ASTM D1418 Designation: CO, ECO

ASTM D2000/SAE J2000 TYPE, CLASS: CH

Apple Compound Designation: EH

Standard Color: Black

Description: Available in homopolymer (CO), copolymer (ECO), and terpolymer (GECO) formats, Epichlorohydrins are oil resistant compounds.

Key Use(s): Ideal for fuel and air conditioning system components. Used in the petroleum industry where a little higher temperature capability than NBR is required.

Temperature Range: Standard Compound: -40° 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° to 275°F). Epichlorohydrin is attacked by ketones; esters; aldehydes; chlorinated and nitro hydrocarbons; and is not recommended for exposure to brake fluids.
