Flame retardant grade of modified methyl methacrylate-butadiene-styrene copolymer not up to standard
Fenómeno del problema
Flame retardant grade of modified methyl methacrylate-butadiene-styrene copolymer is not up to standard; vertical burning or horizontal burning tests fail to pass the target grade
Análisis de la causa
Insufficient flame retardant addition amount
Poor compatibility between flame retardant and methyl methacrylate-butadiene-styrene copolymer, uneven dispersion
Flame retardant decomposes and fails at processing temperature
Improper flame retardant system design
Processing temperature too high, flame retardant degrades
Solución
Increase flame retardant addition amount
Select flame retardants with good compatibility
Select flame retardants stable within the processing temperature range
Optimize flame retardant system design
Control processing temperature to avoid flame retardant degradation
Conclusión clave
Flame retardancy needs to start from addition amount, compatibility, and system design
