Donfoam 812 HCFC-141B isiseko umxube polyols ugwebu block
INTSHAYELELO
I-Donfoam 812 idibanisa iipolyether polyols ezisetyenziselwa ukuvelisa i-PUR block foam.I-foam ineseli efanayo, i-conductivity ephantsi ye-thermal, ukusebenza kwe-thermal insulation ilungile, ukusebenza kwe-flame retardant kulungile, ubushushu obuphantsi akukho ntlupheko ehlayo njl njl.
Isetyenziswe ngokubanzi kwinkqubo yazo zonke iintlobo zomsebenzi wokugquma ezifana: ukwakha udonga lwangaphandle, ukugcinwa okubandayo, iitanki, iipayipi ezinkulu njl.
