PA flame retardancy requires a large amount of flame retardant, and the performance loss is obvious
Sorun Belirtisi
PA flame retardancy requires a large amount of flame retardant, and the performance loss is obvious
Neden Analizi
The molecular structure of PA contains nitrogen, but the self-flame-retardant rating is low, so flame retardants need to be added
Halogen flame retardants have good effects but are environmentally restricted
Halogen-free flame retardants require large addition amounts (15-25%), and the mechanical properties decline significantly
The compatibility between the flame retardant and PA is poor, and dispersion is difficult
The processing fluidity of flame-retardant PA decreases, and the process window is narrower
Çözüm
Select environmentally friendly halogen-free flame retardants
Control the amount of flame retardant added within a reasonable range
Select a flame retardant with good compatibility with polyamide 410 (bio-based long carbon chain nylon)
Adjust the processing parameters after flame retardant modification
Evaluate the balance between flame retardancy and mechanical properties
Temel Çıkarım
PA flame retardancy requires balancing the flame retardant effect and mechanical properties
