Donpanel 423PIR CP / IP puag muab polyols kev nruam PUR
TAW qHIA
DonPanel 423 / PIR yog ib yam ntawm cov muab polyether polyol uas koom tes nrog cyclopentane li foaming neeg sawv cev, yuav siv sij hawm polyol raws li lub ntsiab raw khoom thiab yog tov nrog rau tshwj xeeb pab neeg sawv cev. Nws yog tsim rau thermal rwb thaiv tsev ntawm lub tsev boards, txias cia boards thiab lwm yam products.This khoom tshwj xeeb uas tsim rau tas mus li kab .Tus polyurethane khoom npaj los ntawm reacting nws nrog isocyanate muaj cov nram qab zoo:
- Tsis muaj tsev cog khoom nyhuv thiab yuav tsis ua rau ozone layer
- Zoo fluidity thiab niaj hnub ua npuas ncauj ceev
--Excellent seem stability thiab hluav taws kuj
