Obvious change in melt flowability of polyamide 12 (long carbon chain nylon) after modification (becomes better or
Fenómeno del problema
The melt flowability of polyamide 12 (long carbon chain nylon) changes obviously after modification (becomes better or worse), affecting the processing process window
Análisis de la causa
（1）The added additives change the melt viscosity
（2）The addition amount is too large and the flowability changes excessively
（3）The additive dispersion is uneven and the local viscosity fluctuates
（4）The processing temperature does not match the modified material
（5）Improper lubricant addition
Solución
（1）Adjust the processing parameters to match the flowability after modification
（2）Reasonably control the additive addition amount
（3）Ensure uniform dispersion of the additives
（4）Adjust the temperature according to the modified material
（5）Use lubricants reasonably
Conclusión clave
Flowability changes require process adjustment to match the modified material
