Melt Fluidity of polyamide 46 (high-temperature nylon) Significantly Changed After Modification (Better or Worse)
Fenómeno del problema
The melt fluidity of polyamide 46 (high-temperature nylon) changes significantly after modification (better or worse), affecting the processing process window
Análisis de la causa
The added additive changes the melt viscosity
The amount added is too large, and the fluidity changes excessively
The additive is unevenly dispersed, and the local viscosity fluctuates
The processing temperature does not match the modified material
The lubricant is added improperly
Solución
Adjust the processing parameters to match the fluidity after modification
Reasonably control the amount of additive added
Ensure the additive is evenly dispersed
Adjust the temperature according to the modified material
Use the lubricant reasonably
Conclusión clave
The change in fluidity requires adjusting the process to match the modified material
