ABAK compatibilizer excess
Problem Phenomenon
Excess ABAK compatibilizer causes decreased fluidity and increased brittleness; performance imbalance.
Cause Analysis
Excess ABAK compatibilizer decreases melt fluidity; compatibilizers such as SMA are inherently brittle; excessive addition instead reduces impact performance; suitable addition amount 1-10%, better 3-8%.
Solution
①Control compatibilizer dosage at 3-8%; ②avoid excess; ③balance fluidity and performance; ④testing verification.；after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
The principle of appropriate amount of ABAK compatibilizer is the performance guarantee; excess is harmful; testing determines the optimization point.；after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
