inov muab polyols rau PUR txuas ntxiv
Donpanel 422 HCFC-141b puag muab polyols rau PUR tas li
Taw qhia
DonPanel 422 / PUR sib xyaw polyols yog cov khoom sib xyaw uas muaj cov polyether polyols, surfactants, catalysts, HCFC-141B thiab nplaim hluav taws kub nyhiab hauv qhov sib piv tshwj xeeb.Cov npuas dej muaj cov khoom zoo thermal rwb thaiv tsev, lub teeb hauv qhov hnyav, siab compression lub zog thiab nplaim hluav taws thiab lwm yam zoo.Nws yog dav siv los tsim nruam sandwich panels, corrugated panels thiab lwm yam, uas siv los ua cov khw muag khoom txias, txee, chaw nyob thiab lwm yam.
