PEEK product improper post-crystallization heat treatment
Sorun Belirtisi
Post-crystallization treatment instead causes performance decline or poor effect
Neden Analizi
Heat treatment temperature not high enough or time insufficient, crystallinity not reaching the target; temperature too high causing thermo-oxidative degradation; heating/cooling rate too fast introducing new internal stress
Çözüm
Post-treatment temperature 200-250°C held for 2-4 hours; perform in nitrogen or vacuum protective atmosphere to avoid oxidation; slow heating and cooling <3°C/min
Temel Çıkarım
Post-crystallization heat treatment is a necessary process step to compensate for insufficient crystallization during processing
