Optimization of the phase separation problem of PBD in compounding
Problem Phenomenon
Polybutadiene PBD, as an elastomer toughening modifier or HIPS component, exhibited phase separation-related abnormalities during the compounding process.
Cause Analysis
The Mooney viscosity of PBD affects processing; improper temperature control leads to performance deterioration.
Solution
According to application requirements, add anti-aging agent to systematically solve the problem.
Key Takeaway
The core of PBD processing lies in structure control.
