Large batch differences in melt index of blends
Fenómeno del problema
The melt index of different batches of the same formulation differs by more than 30%
Análisis de la causa
Raw material resin molecular weight fluctuates between batches; the recycled material addition proportion is not fixed; granulation process parameters change
Solución
Establish a raw material incoming inspection system (controlling molecular weight fluctuation); fix the recycled material proportion and source; stabilize granulation process parameters
Conclusión clave
Melt index differences directly affect the '2079851475616104452 process window and product consistency
