Optimization of the degradation problem of PBD in compounding
Problem Phenomenon
Polybutadiene PBD, as an elastomer toughening modifier or HIPS component, exhibited degradation-related abnormalities during the compounding process.
Cause Analysis
The gel content of PBD affects processing; improper shear control leads to performance deterioration.
Solution
According to application requirements, control crosslinking density to systematically solve the problem.
Key Takeaway
The core of PBD processing lies in structure control.
