Weather Resistance of Modified polyamide 6 (nylon 6) Not Up to Standard
Sorun Belirtisi
The weather resistance of modified polyamide 6 (nylon 6) is not up to standard, with yellowing, embrittlement, or significant performance decline after outdoor use
Neden Analizi
No ultraviolet absorber is added or the amount added is insufficient
The antioxidant system is imperfect
The compatibility between the ultraviolet absorber and polyamide 6 (nylon 6) is poor
The antioxidant is consumed and degraded during processing
The formulation design is unreasonable
Çözüm
Add an appropriate amount of ultraviolet absorber (0.2-0.5%)
Improve the antioxidant system with primary/secondary antioxidant coordination
Select a UV absorber with good compatibility
Avoid high-temperature degradation of the antioxidant during processing
Optimize the formulation design
Temel Çıkarım
Weather resistance needs to be addressed from the UV absorber and antioxidant
