Why is ECTFE/ETFE resistant to Nitric Acid?
ECTFE/ETFE shows excellent resistance to Nitric Acid due to its partially fluorinated structure offering broad chemical resistance at high temperatures.
⚠️ When NOT to use ECTFE/ETFE
Avoid using ECTFE/ETFE Fluoropolymer with very few chemicals — mainly hot amines and sodium above certain concentrations. Excellent up to 150°C.
