Le PVC-U rigide résiste aux acides dilués et concentrés (sauf HNO3 fumant), aux bases et solutions salines. Sensible aux solvants aromatiques, THF, DMF et cétones. Le CPVC (version chlorée) offre une meilleure tenue thermique et chimique.

Frequently asked questions
Injection at 160–200 °C — thermal degradation releasing HCl above 210 °C. Mould at 20–60 °C. Material corrosive to moulds → stainless or heat-treated steels. Low shrinkage (0.2–0.6 %).
PVC (code 3) is mechanically recyclable. Specialised channels exist for window profiles (the VinylPlus programme in Europe). The presence of additives complicates recycling.
Plasticised flexible PVC is not recommended for food contact (phthalates). Rigid PVC grades without phthalates may be compliant for certain applications. Prefer PP or PE for food applications.
