China Donfoam 812 HCFC-141B base lwemenu polyols for block isiponji yoMvelisi kunye Supplier

Donfoam 812 HCFC-141B base lwemenu polyols for block amagwebu

Donfoam 812 HCFC-141B base lwemenu polyols for Image block amagwebu Ifakwe

Inkcazo elifutshane:

Donfoam 812 ufane polyether polyols esetyenziselwa yemveliso iPuri block amagwebu. Le amagwebu iye iseli uniform, conductivity thermal ephantsi, ukusebenza yokwambathisa thermal ilungile, intsebenzo nelangatye nekudodobalisa na sihlwahlwaz elungileyo, akukho kubushushu obuphantsi lincipha njl

Luphawu asetyenziswe kwinkqubo zonke iintlobo zomsebenzi yokwambathisa ezifana: ekwakheni udonga lwangaphandle, ukugcinwa ebandayo, amatanki, imibhobho emikhulu njl
