Why is Polysulfone resistant to Oxalic Acid?
Polysulfone shows excellent resistance to Oxalic Acid due to its sulfone group providing thermal and chemical stability up to 150°C.
⚠️ When NOT to use Polysulfone
Avoid using Polysulfone (PSU) with ketones, esters, and chlorinated solvents. Excellent for hot water and steam applications.
