Why is PVC Flexible resistant to Glycerin?
PVC Flexible shows good resistance to Glycerin 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.
