Unsatisfactory Toughening Effect of Modified polyamide 46 (high-temperature nylon)

Fenómeno do problema
The toughening effect of modified polyamide 46 (high-temperature nylon) is unsatisfactory, and the impact strength improvement is lower than the expected target
Análise das causas
The amount of toughening agent added is insufficient or the dispersion is uneven The compatibility between the toughening agent and the matrix is poor, and the interfacial bonding is weak The processing temperature is improper (deviating from 290-330°C), and the toughening agent degrades or is poorly dispersed The mixing is insufficient, and the toughening agent agglomerates The particle size of the toughening agent does not match
Solução
Increase the amount of toughening agent to a reasonable ratio Select a toughening agent with good compatibility with polyamide 46 (high-temperature nylon) Reasonably set the processing temperature within the range of 290-330°C Strengthen mixing to ensure uniform dispersion Select a toughening agent with a suitable particle size
Conclusão principal
The toughening effect needs to be addressed from the amount added, compatibility, and dispersion
