Why is EPDM resistant to Sulfuric Acid?

EPDM shows good resistance to Sulfuric 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.
