Compatibility Rating
At 20°C (68°F)
Good
Good resistance - suitable for intermittent contact
At 50°C (122°F)
Fair
Limited resistance - short-term exposure only
Why is Polysulfone resistant to Dioxane?
Polysulfone shows good resistance to Dioxane 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.
