Viscosity fluctuation problem of PBS biodegradable material in coating
Problem Phenomenon
Polybutylene succinate PBS shows viscosity fluctuation in coating processing at 140-200°C.
Cause Analysis
Caused by poor thermal stability of PBS and fast degradation.
Solution
Improved by adding an anti-hydrolysis agent.
Key Takeaway
The degradation characteristics of PBS require gentle processing.
