China Donfoam 812 HCFC-141B base lenhlanganisela polyols block Foam Umkhiqizi kanye Umthengisi

Donfoam 812 HCFC-141B base lenhlanganisela polyols block Foam

Donfoam 812 HCFC-141B base lenhlanganisela polyols for Image block Foam Efakiwe

Incazelo emfushane:

Donfoam 812 lenhlanganisela polyether polyols esetshenziselwa umkhiqizo lePhure block Foam. I Foam kweseli iyunifomu, ongaphakeme conductivity ezishisayo, ezishisayo ukwahlukanisa ukusebenza kuhle, ilangabi cishe yizona ezisetshenziswa kabanzi ukusebenza kuhle, izinga lokushisa ongaphakeme kungekho zincipha ufa njll

Kabanzi inqubo zonke izinhlobo zomsebenzi ukwahlukanisa ezifana: ukwakha udonga lwangaphandle, indawo ebanda kakhulu, amathangi, amapayipi amakhulu njll
