Chemical Resistant EPDM O-rings

Size: Standard and Custom made

Material: Peroxide cure EPDM, others

Main characteristics of EPDM O ring

Influenced by its molecular structure (the main chain is composed of chemically stable saturated hydrocarbons, and only unsaturated double bonds are contained in the side chain), EPDM has extraordinary resistance to oxidation, aging, ozone and corrosion

EPDM is essentially non polar, so EPDM EPDM has strong resistance to polar solutions and chemicals, as well as good insulation properties, but poor water tightness

Corrosion resistance

Due to the lack of polarity and low Degree of unsaturation of Ethylene propylene rubber, it has good resistance to various polar chemicals such as alcohol, acid, alkali, oxidant, refrigerant, detergent, animal and vegetable oil, ketone and grease; But it has poor stability in fatty and aromatic solvents (such as gasoline, benzene, etc.) and mineral oils. Under the long-term action of concentrated acid, the performance will also decrease.
