ASA and PA66 Blending for Weather Resistance
Fenómeno do problema
【Problem Phenomenon】PA66 outdoor parts absorb water and have poor weather resistance, performance decays quickly
Análise das causas
Blending ASA with PA66 can improve PA66 weather resistance: ASA acrylic component provides UV protection, combined with HALS and antioxidants for further stabilization; compatibilizer improves interface
Solução
PA66 outdoor parts evaluate ASA blending modification; add HALS and antioxidants for synergy; interface compatibility verification; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusão principal
ASA makes up PA66's weather resistance shortcoming, blending plus stabilizer synergy; 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 subsequent similar problems
