Plasticizer migration during PLA processing
Fenómeno do problema
The plasticizer in PLA products migrates to the surface over time, producing a greasy feeling.
Análise das causas
The low molecular plasticizer has limited compatibility with PLA and gradually migrates.
Solução
Use macromolecular plasticizers or reactive plasticizers to reduce migration.
Conclusão principal
PLA plasticizer migration affects the product surface and use safety.
