COC Comparison with PMMA
문제 현상
COC's optical performance is comparable to PMMA, but its heat resistance and dimensional stability are better.
원인 분석
COC's optical performance can rival PMMA; its heat resistance is better than PC; its water absorption is far lower than PMMA; its dimensional stability is even better; its density is 10% lower; its water vapor tightness is good; its rigidity and heat resistance are improved.
해결 방법
①Performance comparison utilization; ②heat resistance and dimensional advantages; ③low water absorption advantage; ④lightweighting; ⑤application selection.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
핵심 요약
The comparison of COC with PMMA is the basis of replacement decisions; the comprehensive advantages are the value; selection ensures application success.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
