Why is EPDM resistant to Barium Hydroxide?
EPDM shows excellent resistance to Barium Hydroxide 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.
