COC Glass Transition Temperature Tg
문제 현상
COC has a high glass transition temperature of 140-170℃, a heat resistance advantage, and processing temperature management.
원인 분석
The rigid ring structure of the COC main chain is extremely rigid; it presents a relatively high glass transition temperature; Tg rises with increasing cyclic olefin monomer insertion rate; in the range of 140-170℃; its heat resistance is better than PC.
해결 방법
①Utilize the high Tg heat resistance advantage; ②processing temperature matching; ③Tg grade selection; ④thermal management; ⑤performance verification.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
COC's high Tg is a heat resistance advantage; processing temperature matching is the key; verification ensures performance.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
