At 50°C
Poor
Not recommended - significant degradation expected
Why is PVC Rigid resistant to Urea?
PVC Rigid shows good resistance to Urea due to its chlorinated structure providing resistance to acids, alkalis, and many inorganic chemicals.
⚠️ When NOT to use PVC Rigid
Avoid using PVC (Rigid) with ketones, esters, aromatic and chlorinated solvents. Maximum temperature around 60°C.
