Donfoam 812 HCFC-141B saldhigga waxay isku daraan polyols loogu talagalay xannibaadda xumbo
HORDHAC
Donfoam 812 isku darka polyether-ka loo isticmaalo soo saarista xumbo xannibaadda PUR.Xumbadu waxay leedahay unug isku mid ah, kororka kulaylka hooseeya, waxqabadka kuleylka kuleylka ayaa wanaagsan, waxqabadka ololka waa mid wanaagsan, heerkul hoose oo aan dillaacin iwm.
Si ballaaran loo isticmaalo habka dhammaan noocyada shaqada dahaadhka sida: dhismaha derbiga dibadda, kaydinta qabowga, taangiyada, tuubooyinka waaweyn iwm.
