PPS vs. PEEK Comparison
Problembeschreibung
Selection between PPS and PEEK for high-temperature parts is a dilemma; performance and cost are hard to balance
Ursachenanalyse
PEEK is superior to PPS in heat resistance, toughness, and wear resistance but costs several times more; PPS is comparable in chemical resistance and flame retardancy but more brittle; below 200°C, PPS wins on cost-performance
Lösung
①Prioritize PPS for rigid parts below 220°C; ②Select PEEK for high toughness, high wear resistance, or ultra-high temperature; ③Evaluate by full lifecycle cost; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
The watershed between PPS and PEEK is temperature and toughness; below 220°C, PPS is the king of cost-performance; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
