Low-temperature brittleness of PMMA products
Fenómeno del problema
PMMA impact strength drops greatly at low temperatures and becomes brittle.
Análisis de la causa
PMMA β transition temperature is about 20-40°C; at low temperatures, molecular chain segment motion is restricted and embrittlement is aggravated.
Solución
Use toughened grade PMMA; avoid notches and sharp corners in product design.
Conclusión clave
PMMA is limited in low-temperature applications.
