Donpipe 322 HCFC-141b mimọ parapo polyols fun opo ikarahun
Mo NTRODUCTION
DonPipe 322 ni a irú ti parapo polyols pẹlu hcfc-141b bi ifofó oluranlowo, mu polyol bi awọn ifilelẹ ti awọn aise awọn ohun elo, dapọ pẹlu pataki kan oluranlowo. Yi awọn ohun elo ti o dara fun lode gbona idabobo nlanla ti o ti wa ni lilo fun omi, epo ati gaasi pipelines .Awọn polyurethane ọja pese sile nipa reacting o pẹlu isocyanate ni o ni awọn wọnyi anfani:
- ti o dara compressive agbara ati onisẹpo iduroṣinṣin
- ga sunmọ-cell oṣuwọn ati ti o dara mabomire išẹ
- ti o dara idabobo išẹ
