Compatibility Rating

📊 Note: Formaldehyde resistance varies by concentration. Data available for: 10 %, 30 %, 40 %. Search for specific concentrations →

At 20°C (68°F)
B
Good
Good resistance - suitable for intermittent contact
At 50°C (122°F)
C
Fair
Limited resistance - short-term exposure only

Why is Polysulfone resistant to Formaldehyde?

Polysulfone shows good resistance to Formaldehyde 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.
