Insufficient thermal stability caused by improper antioxidant type, dosage, and combination
Sorun Belirtisi
Insufficient thermal stability caused by improper antioxidant type, dosage, and combination
Neden Analizi
（1）The primary antioxidant addition amount is insufficient
（2）The primary/secondary antioxidant combination ratio is improper
（3）The antioxidant partially fails at the processing temperature
（4）The antioxidant has poor compatibility with polyamide (general-purpose nylon) and disperses poorly
（5）Antioxidant consumption accumulates during multiple processings
Çözüm
（1）Add 0.1-0.3% of primary antioxidant
（2）Primary/secondary antioxidant combined at 1:2
（3）Select antioxidants that are stable within the processing temperature range
（4）Ensure uniform dispersion of the antioxidants
（5）Supplement antioxidants when using regrind
Temel Çıkarım
PA anti-oxidation requires primary/secondary combination and high-temperature stability
