PCABS Flame Retardant Selection
Fenómeno del problema
PC/ABS flame retardant types affect performance and processing; comparison of halogen, phosphorus, nitrogen, and inorganic types.
Análisis de la causa
PC/ABS flame retardants: halogen (bromine) moderately reduces strength, has good flame retardancy but produces corrosive gas; phosphorus-based has little impact on strength, good char formation, easy processing, and is environmentally friendly; nitrogen-based slightly reduces rigidity, with low smoke and low toxicity; inorganic aluminum trihydrate has high filling, wears equipment, but is non-toxic.
Solución
①Select according to performance and environmental protection; ②phosphorus-based preferred; ③evaluate halogen restrictions; ④pay attention to high filling of inorganic types; ⑤compliance confirmation.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Conclusión clave
PCABS flame retardant selection is a balance of performance and environmental protection; phosphorus-based is the mainstream direction; compliance ensures market access.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
