Insufficient anti-dripping of PET flame retardant formulations
Sorun Belirtisi
PET flame retardant products show molten dripping in combustion tests and fail to reach the V-0 standard.
Neden Analizi
Only halogen flame retardant is added without an anti-dripping agent (PTFE); melt viscosity is low during combustion and dripping is easy.
Çözüm
Add 0.3-0.5% PTFE anti-dripping agent; use char-forming agents to promote charring; optimize the flame retardant system ratio.
Temel Çıkarım
PET flame retardancy requires the synergistic action of char formation and anti-dripping to reach V-0.
