Donfoam 824PIR HFC-245fa puag muab polyols rau PIR nruam nruam ua npuas ncauj
Taw qhia
DonFoam 824 / PIR yog ib hom kev sib xyaw polyols siv hfc-245fa foaming tus neeg sawv cev, nrog polyol ua cov khoom siv tseem ceeb, sib xyaw nrog tus neeg sawv cev tshwj xeeb, tsim nyog rau kev rwb thaiv tsev ntawm kev tsim kho, kev thauj mus los, plhaub thiab lwm yam khoom.Cov khoom siv no yog tsim tshwj xeeb rau cov kab nruam .Cov khoom siv polyurethane npaj los ntawm reacting nws nrog isocyanate muaj cov hauv qab no zoo:
-- Eco-friendly, tsis ua kom puas ozone txheej
- Siab compressive zog thiab zoo homogeneity ntawm isotropic zog
- Zoo heev thermal rwb thaiv tsev kev ua tau zoo thiab qhov ntev stability
