TPU Low-Temperature Resistance
Problembeschreibung
TPU products remain elastic in severe cold environments while other elastomers have already embrittled
Ursachenanalyse
Polyether-type TPU glass transition temperature can be as low as below -60°C, maintaining excellent elasticity in severe cold environments; suitable for equipment and vehicle sealing in cold regions; when troubleshooting on site, verify item by item according to this mechanism to avoid blindly adjusting the machine based only on experience
Lösung
①Choose polyether-type TPU for severe cold environments; ②Verify below -40°C for low-temperature working conditions; ③Exploit the low-temperature advantage for seals in high-cold regions; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
TPU's low-temperature resistance is the trump card of the polyether type; remaining elastic below -60°C, it is the default choice for high-cold applications; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
