PPSU long-term hot water aging
Problem Phenomenon
After long-term immersion in 95°C hot water, the mechanical properties of PPSU decline.
Cause Analysis
Although PPSU is hydrolysis resistant, slow hydrolysis still occurs under ultra-long-term high-temperature water.
Solution
Consider hot water aging in service life assessment.
Key Takeaway
PPSU long-term hot water performance needs verification.
