Molecular chain breakage caused by PLA hydrolysis
Fenómeno do problema
The molecular weight of PLA drops sharply in a water-containing environment.
Análise das causas
The ester bonds hydrolyze and break the molecular chains; the higher the temperature, the faster the hydrolysis.
Solução
Fully dry the raw material; add an anti-hydrolysis agent; avoid high-temperature and high-humidity environments.
Conclusão principal
PLA hydrolysis is its main degradation pathway.
