PBS biodegradable material shrinkage deformation problem in spinning
Problem Phenomenon
Polybutylene succinate (PBS) exhibits shrinkage deformation during spinning processing at 140-200°C.
Cause Analysis
Caused by poor thermal stability and abnormal flow of PBS.
Solution
Improve by sufficient drying.
Key Takeaway
The degradation characteristics of PBS require mild processing.
