Flame Retardant Rating of Modified polyamide 6 (nylon 6) Not Up to Standard
Problem Phenomenon
The flame retardant rating of modified polyamide 6 (nylon 6) is not up to standard, and the vertical burning or horizontal burning test does not pass the target rating
Cause Analysis
The amount of flame retardant added is insufficient
The compatibility between the flame retardant and polyamide 6 (nylon 6) is poor, and the dispersion is uneven
The flame retardant decomposes and fails at the processing temperature
The flame retardant system design is improper
The processing temperature is too high, and the flame retardant degrades
Solution
Increase the amount of flame retardant
Select a flame retardant with good compatibility
Select a flame retardant that is stable within the processing temperature range
Optimize the flame retardant system design
Control the processing temperature to avoid flame retardant degradation
Key Takeaway
Flame retardancy needs to be addressed from the amount added, compatibility, and system design
