Incomplete thermal imidization
문제 현상
The imidization degree of PI is lower than the target value and performance is substandard
원인 분석
Final heat treatment temperature not high enough or time insufficient; PAA film/product too thick, internal temperature uneven
해결 방법
Ensure the final treatment temperature is ≥300°C and hold for a sufficient time; confirm the imidization characteristic peaks by IR spectroscopy (1780/1720/1380 cm⁻¹); control the sample thickness
핵심 요약
The imidization degree (imidization rate) determines the final performance of PI
