Polyether na Musamman - Ƙananan Nauyin Kwayoyin Halitta na Pet Polyether
Kadarori da Amfani
Ruwa ne a zafin ɗaki, wanda ya dace a yi amfani da shi da kuma sarrafawa. Zafin canja wurin gilashi na -80 ℃, tare da kyakkyawan aikin ƙarancin zafin jiki, halayen injinan samfuran elastomer da PTMG kusa da PTMG, na iya maye gurbin PTMG a cikin yanayi mai zafi na ƙarancin zafin jiki.
Da kyakkyawan sassaucin kwayoyin halitta, zai iya maye gurbin PTMG a cikin fata mai laushi da tawada ta bugawa; ana iya amfani da shi a cikin manne masu jure yanayin zafi mai ƙarancin zafi, shafi, polyurethane elastomers da sauransu.
