Why is EPDM resistant to Calcium Chloride?
EPDM shows excellent resistance to Calcium Chloride 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.
