PBD antioxidant selection Regulation and Processing Stability
Problem Phenomenon
PBD exhibits antioxidant selection-related process abnormalities in extrusion blending.
Cause Analysis
Under the PBD processing temperature of 140-180°C, improper setting of the antioxidant selection parameters leads to Mooney viscosity drift.
Solution
Optimize the antioxidant selection and reduce the shear strength.
Key Takeaway
In PBD processing, antioxidant selection control is the foundation of quality stability.
