Viscosity fluctuation problem of PBS biodegradable material in spinning
Problem Phenomenon
Polybutylene succinate PBS shows viscosity fluctuation in spinning processing at 140-200°C.
Cause Analysis
Caused by poor thermal stability of PBS and slow crystallization.
Solution
Improved by shortening the residence time.
Key Takeaway
The degradation characteristics of PBS require gentle processing.
