TPE Oil Additive Exudation
Sorun Belirtisi
Oily exudate appears on the product surface, feeling sticky to the touch.
Neden Analizi
Oil additives in SEBS-based TPE exude to the surface when the temperature is too high; the higher the processing temperature, the more obvious the exudation.; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blind machine adjustment based solely on experience
Çözüm
①Control the processing temperature not too high; ②evaluate oil type and content; ③confirm formulation temperature resistance with the supplier; ④observe recurrence after wiping.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Temel Çıkarım
SEBS-based TPE most fears oil exudation caused by excessive temperature; this forms a sharp contrast with TPU's shear sensitivity.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
