Why is EPDM rated this way to Lactic Acid?
EPDM has limited resistance to Lactic Acid. Short-term exposure may be acceptable, but prolonged contact is not recommended.
⚠️ When NOT to use EPDM
Avoid using EPDM Rubber with mineral oils, petroleum fuels, and aromatic solvents which cause swelling and degradation.
