Unsatisfactory toughening effect of modified polyamide 12 (long carbon chain nylon)
Fenómeno del problema
The toughening effect of modified polyamide 12 (long carbon chain nylon) is unsatisfactory, and the impact strength improvement is lower than the expected target
Análisis de la causa
（1）The toughening agent addition amount is insufficient or the dispersion is uneven
（2）The toughening agent has poor compatibility with the matrix and the interfacial bonding is weak
（3）Improper processing temperature (deviation from 190-230°C) causes the toughening agent to degrade or disperse poorly
（4）Insufficient mixing causes the toughening agent to agglomerate
（5）The toughening agent particle size does not match
Solución
（1）Increase the toughening agent addition amount to a reasonable ratio
（2）Select a toughening agent with good compatibility with polyamide 12 (long carbon chain nylon)
（3）Reasonably set the processing temperature within the range of 190-230°C
（4）Strengthen mixing to ensure uniform dispersion
（5）Select a toughening agent with a suitable particle size
Conclusión clave
The toughening effect needs to be addressed from the addition amount, compatibility, and dispersion
