PC/ABS flame retardant exudation
Problem Phenomenon
Exudates appear on the surface.
Cause Analysis
Flame retardant migrates and exudes; too high temperature accelerates it.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based on experience alone; this mechanism has been repeatedly verified by industry data and should be confirmed first during troubleshooting
Solution
①Control temperature; ②evaluate flame retardant system; ③confirm with supplier; ④observe recurrence.; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
Exudation points to additive migration; formula confirmation is fundamental.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later
