Plasticizer migration during PLA processing
Fenómeno del problema
The plasticizer in PLA products migrates to the surface over time, producing a greasy feeling.
Análisis de la causa
The low molecular plasticizer has limited compatibility with PLA and gradually migrates.
Solución
Use macromolecular plasticizers or reactive plasticizers to reduce migration.
Conclusión clave
PLA plasticizer migration affects the product surface and use safety.
