PBD molecular weight Regulation and Processing Stability
Problem Phenomenon
PBD exhibits molecular weight-related process abnormalities in internal mixing.
Cause Analysis
Under the PBD processing temperature of 140-180°C, improper setting of the molecular weight parameters leads to gel generation.
Solution
Optimize the molecular weight and add antioxidant 2246.
Key Takeaway
In PBD processing, molecular weight control is the foundation of quality stability.
