Donpanel 422 HCFC-141b puag muab polyols kev nruam PUR
TAW qHIA
DonPanel 422 / PUR muab polyols yog ib tug compound uas muaj polyether polyols, surfactants, catalysts, HCFC-141B thiab nplaim retardant nyob rau hauv ib tug tshwj xeeb piv. Cov ua npuas ncauj muaj zoo thermal rwb thaiv tsev vaj tse, lub teeb nyob rau hauv hnyav, siab compression zog thiab nplaim retardant thiab lwm yam zoo. Nws yog dav siv los tsim tas mus li nyuaj panels, corrugated panels thiab lwm yam, uas siv los mus ua kom txias khw muag khoom noj, khoom, portable tsev thiab thiaj li nyob.
