PPS product heat resistance application
Problem Phenomenon
Performance requirements in high-temperature environments.
Cause Analysis
PPS long-term use temperature above 200℃ is a core advantage; grade and crystallinity determine actual performance.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Select high heat-resistant grade; ②ensure crystallinity; ③thermal aging verification; ④select material by working conditions.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPS heat resistance advantage is realized through selection and crystallization management.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for subsequent similar problems
