Low low-temperature impact strength of PLA
Fenómeno del problema
PLA products have low impact strength at low temperature (<0°C) and are easy to break.
Análisis de la causa
The inherent brittleness of PLA is more prominent at low temperature; Tg is about 55-60°C, and below Tg the molecular chain movement is severely restricted.
Solución
Use toughened modified PLA; avoid notches in product design; do not use in low-temperature impact applications.
Conclusión clave
The low-temperature brittleness of PLA is its inherent weakness.
