Donpanel 412 HCFC-141b puag muab polyols rau PUR
kuv NTRODUCTION
DonPanel 412 muab polyols yog ib tug compound uas muaj polyether polyols, surfactants, catalysts 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 nyuaj daim hlau, corrugated daim hlau thiab lwm yam, uas siv los mus ua kom txias khw muag khoom noj, khoom, portable tsev thiab thiaj li nyob.
