COC Low Water Absorption
Problem Phenomenon
COC's water absorption is <0.01%, its dimensional stability is excellent, but management is still required.
Cause Analysis
COC's water absorption <0.01% is far lower than PMMA and PC; its dimensional stability is excellent; it hardly absorbs water; it will not produce property decline caused by water absorption; but surface-adhered water management.
Solution
①Utilize the low water absorption advantage; ②surface-adhered water management; ③dimensional stability verification; ④environmental control; ⑤quality assurance.; After adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
COC low water absorption is the core advantage of dimensional stability; surface management is the detail; verification ensures precision applications.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
