Optimization of the discoloration problem of PBD in extrusion
Problem Phenomenon
Polybutadiene PBD, as an elastomer toughening modifier or HIPS component, exhibited discoloration-related abnormalities during the extrusion process.
Cause Analysis
The vinyl content of PBD affects processing; improper oxidation control leads to performance deterioration.
Solution
According to application requirements, optimize the compounding process to systematically solve the problem.
Key Takeaway
The core of PBD processing lies in thermal-oxidative protection.
