Donpanel 415 HFC-365mfc puag muab polyols rau PUR
INTRODUCTION
DonPanel 415 yog ib hom kev sib xyaw polyether polyols nrog HFC-245fa ua tus neeg sawv cev foaming, noj 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 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
- Zoo heev rwb thaiv tsev, qhov ntev stability thiab adhesion
