I-China Donfoam 812 HCFC-141B inhlanganisela ye-polyols ye-block foam Umkhiqizi Nomhlinzeki

Donfoam 812 HCFC-141B base blend polyols for block Foam

I-Donfoam 812 HCFC-141B ehlanganisa i-polyols ye-block Foam Isithombe Esifakiwe

Incazelo emfushane:

I-Donfoam 812 ihlanganisa i-polyether polyols esetshenziselwa ukukhiqiza igwebu lebhulokhi le-PUR. Igwebu linamaseli afanayo, ukuhanjiswa kwe-thermal okuphansi, ukusebenza kwe-thermal insulation kuhle, ukusebenza kwe-flame retardant kuhle, izinga lokushisa eliphansi alikho ukushwabana okunciphayo njll.

Isetshenziswa kabanzi kwinqubo yazo zonke izinhlobo zomsebenzi wokufakelwa okufana nokwakhiwa kodonga lwangaphandle, isitoreji esibandayo, amathangi, amapayipi amakhulu njll.
