China Donpanel 412 HCFC-141b base lenhlanganisela polyols ngoba lePhure Umkhiqizi kanye Umthengisi

Donpanel 412 HCFC-141b base lenhlanganisela polyols ngoba lePhure

Incazelo emfushane:

DonPanel 412 lenhlanganisela polyols kuyinto ekhuthaza esakhiwa polyols polyether, surfactants, yelikhono nelangabi cishe yizona ezisetshenziswa endaweni isilinganiso ekhethekile. I Foam has okuhle ezishisayo ukwahlukanisa impahla, ukukhanya isisindo, amandla okusezingeni eliphezulu kokucindezelwa nelangabi cishe yizona ezisetshenziswa kabanzi nokunye. It is kabanzi ukukhiqiza isangweji amapuleti, amapuleti lukathayela njll, okubhekisele izitolo ezibandayo, amakhabethe, zokukhosela ephathekayo nokunye ukwenza.
