Why is PVC Flexible resistant to Potassium Chloride?
PVC Flexible shows excellent resistance to Potassium Chloride due to similar chemistry to rigid PVC but with plasticizers that can be extracted by some solvents.
⚠️ 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.
