Donpipe 322 HCFC-141b puag muab polyols rau lub plhaub plhaub
INTRODUCTION
DonPipe 322 yog ib hom kev sib xyaw polyols nrog hcfc-141b ua tus neeg sawv cev foaming, noj polyol ua cov khoom siv tseem ceeb, sib xyaw nrog cov koom haum tshwj xeeb.Cov khoom siv no tsim nyog rau cov txheej txheem thermal rwb thaiv tsev uas yog siv rau cov kav dej, roj thiab roj .Cov khoom siv polyurethane npaj los ntawm reacting nws nrog isocyanate muaj cov hauv qab no zoo:
-- zoo compressive zog thiab seem stability
- siab kaw-cell tus nqi thiab zoo waterproof kev ua tau zoo
-- zoo rwb thaiv tsev kev ua tau zoo
