ABAK antioxidant system
Problem Phenomenon
ABAK antioxidants (1010/168) are compounded to prevent oxidation of ABS and PA.
Cause Analysis
ABAK antioxidant 1010 prevents oxidation of ABS/SAN, 168 prevents oxidation of PA; compounding ratio 1:1; addition amount 0.1-0.3%; thermal-oxidative aging protection; long-term performance.
Solution
①Antioxidant compounding system; ②addition amount optimization; ③processing dispersion; ④aging testing; ⑤long-term tracking.；after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
ABAK antioxidant compounding is targeted protection; ratio and dosage are optimized; testing verifies the effect.；after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
