Donfoam 822PIR HCFC-141B Base Blend Pollols for okuqhubekayo PIR block Foam
Ukuqalisa
Donfoam 822 / PIR uhlobo lwe-blend polyols nge-HCFC-141B ejenti, nge-polylol njenge-ejenti ekhethekile esetshenziswayo, edingwa yi-polyurethane elungiselelwe ngokukhethekile nge-isocyanate inezinzuzo ezilandelayo:
1. I-Foam inamandla afanayo kanye nokuqina kobukhulu kuzo zonke izinkomba
2. Imikhiqizo ye-FOAM ingagawulwa ibe yizifani ezahlukahlukene ngokuya ngezidingo zomkhiqizo
3. Ukusebenza okuhle kakhulu kokufakwa okushisayo
