Why is PVC Flexible rated this way to Propionic Acid?
PVC Flexible has limited resistance to Propionic Acid. Short-term exposure may be acceptable, but prolonged contact is not recommended.
⚠️ When NOT to use PVC Flexible
Avoid using PVC (Flexible/Plasticized) with the same solvents as rigid PVC, plus any chemical that extracts plasticizers. Generally less resistant than rigid PVC.
