TPU product low-temperature hardening
Fenómeno del problema
The product hardens and elasticity decreases in cold environments.
Análisis de la causa
Soft segment crystallization or vitrification of TPU at low temperature affects elasticity; low-temperature performance varies greatly between grades; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
①select low-temperature resistant grades; ②do low-temperature test verification; ③evaluate formulation influence; ④manage the use temperature range; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
For low-temperature applications, select materials according to the grade's low-temperature performance; test verification is indispensable; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later
