Why is EPDM resistant to Hydrochloric Acid?

EPDM shows excellent resistance to Hydrochloric Acid due to its saturated polymer backbone resisting degradation from water, steam, acids, and alkalis.

⚠️ When NOT to use EPDM

Avoid using EPDM Rubber with mineral oils, petroleum fuels, and aromatic solvents which cause swelling and degradation.
