Donfoam 812 HCFC-141B Base Blend Pollols for block foam
Ukuqalisa
Donfoam 812 Blend polytheate polyols esetshenziselwa ukukhiqiza i-pur block Foam. Igwebu lineseli elifanayo, ukuvumelanisa okushisayo okuphansi, ukusebenza okushisayo kokufakwa kwe-inhle, ukusebenza kwe-flame retardant kuhle, izinga lokushisa eliphansi akukho okunciphayo kwe-crack njll.
Kusetshenziswe kahle kwinqubo yazo zonke izinhlobo zomsebenzi wokufakelwa njenge: Ukwakha udonga lwangaphandle, ukugcinwa okubandayo, amathangi, amapayipi amakhulu njll.
