Donpanel 423PIR CP / IP puag muab polyols rau PUR txuas ntxiv
Taw qhia
DonPanel 423 / PIR yog ib hom kev sib xyaw polyether polyol uas siv cyclopentane ua tus neeg sawv cev ua npuas dej, siv polyol ua cov khoom siv tseem ceeb thiab sib xyaw nrog tus neeg sawv cev tshwj xeeb.Nws yog tsim rau thermal rwb thaiv tsev ntawm lub tsev boards, txias cia boards thiab lwm yam khoom.Cov khoom no yog tsim tshwj xeeb rau cov kab nruam .Cov khoom polyurethane npaj los ntawm reacting nws nrog isocyanate muaj cov nram qab no zoo:
-- Tsis muaj cov nyhuv tsev cog khoom thiab tsis ua rau lub ozone txheej
- Zoo fluidity thiab uniform foam ntom
--Txoj kev ruaj ntseg zoo thiab hluav taws kub
