PBD molecular weight Regulation and Processing Stability
Problembeschreibung
PBD exhibits molecular weight-related process abnormalities in extrusion blending.
Ursachenanalyse
Under the PBD processing temperature of 140-180°C, improper setting of the molecular weight parameters leads to Mooney viscosity drift.
Lösung
Optimize the molecular weight and introduce nitrogen protection.
Wichtigste Erkenntnis
In PBD processing, molecular weight control is the foundation of quality stability.
