Flame retardant rating of modified polyamide (general-purpose nylon) not up to standard
Fenómeno del problema
The flame retardant rating of modified polyamide (general-purpose nylon) is not up to standard, and the vertical burning or horizontal burning test fails to pass the target rating
Análisis de la causa
（1）The flame retardant addition amount is insufficient
（2）The flame retardant has poor compatibility with polyamide (general-purpose nylon) and the dispersion is uneven
（3）The flame retardant decomposes and fails at the processing temperature
（4）Improper flame retardant system design
（5）The processing temperature is too high and the flame retardant degrades
Solución
（1）Increase the flame retardant addition amount
（2）Select a flame retardant with good compatibility
（3）Select a flame retardant that is stable within the processing temperature range
（4）Optimize the flame retardant system design
（5）Control the processing temperature to avoid flame retardant degradation
Conclusión clave
Flame retardancy needs to be addressed from the addition amount, compatibility, and system design
