Why is EPDM rated this way to Acetaldehyde?
EPDM has limited resistance to Acetaldehyde. 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.
