PBD molecular weight Regulation and Processing Stability
Fenómeno del problema
PBD exhibits molecular weight-related process abnormalities in extrusion blending.
Análisis de la causa
Under the PBD processing temperature of 140-180°C, improper setting of the molecular weight parameters leads to Mooney viscosity drift.
Solución
Optimize the molecular weight and introduce nitrogen protection.
Conclusión clave
In PBD processing, molecular weight control is the foundation of quality stability.
