Optimization of the phase separation problem of PBD in extrusion
Problem Phenomenon
Polybutadiene PBD, as an elastomer toughening modifier or HIPS component, exhibited phase separation-related abnormalities during the extrusion process.
Cause Analysis
The Mooney viscosity of PBD affects processing; improper crosslinking 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.
