Polyether na musamman - matsakaicin 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 injin na elastomer suna kusa da na PTMG.
Ana amfani da shi galibi a cikin tsarin samar da sinadarai masu ƙarfi, tare da kyawawan halayen injina masu ƙarancin zafin jiki da kuma yanayin zafi mai yawa.
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.
