EPDM O-Rings Typical Applications and Products:
Ethylene-Propylene elastomers are most commonly available as EPR, a copolymer of ethylene and propylene, and EPDM, a terpolymer. EPR and EPDM have very similar properties and the abbreviations are often used interchangeably. EPDM can be cured with either Sulphur or Peroxide. Sulphur curing is less expensive and easier to process but the product may be tacky and can exhibit some bloom. Peroxide curing is more difficult to process but provides better chemical, thermal, and aging resistance.
EPDM is a versatile and relatively inexpensive material. It is often used in drinking water systems due to its Chlorine and Chloramine resistance and in hydraulic and braking systems due to its excellent Glycol resistance. Other common uses include Medical and Pharmaceutical applications and Food and Dairy applications. EPDM is available in o-rings, sheets, gaskets, custom molded products or extruded as solid or sponge. Hardness ranges from 40 Shore A to 90 Shore A. Special grades with military approvals are also available. EPDM has poor resistance and should not be used with most petroleum and mineral oil products. Specialty formulations with Y267 (L’Garde) cure are used in high temperature and pressure steam environments in geothermal applications.
40 to 90 Shore A are available.
