HDPE product low-temperature brittle cracking
Fenómeno del problema
HDPE products crack when used in winter.
Análisis de la causa
HDPE has high crystallinity and reduced low-temperature toughness; notch-sensitive, sharp corners easily crack at low temperature.
Solución
①Select high-impact grades for low-temperature applications; ②eliminate sharp corners in the structure; ③conduct low-temperature drop verification; ④avoid large deformation assembly at low temperature.
Conclusión clave
Low-temperature applications: grade selection + rounded corners as double insurance.
