Donpipe 303 CP / IP puag muab polyols rau kev rwb thaiv tsev kav
Taw qhia
Donpipe 303 yog ib hom kev sib xyaw polyols ua npuas ncauj rau cov yeeb nkab rwb thaiv tsev, nrog cyclopentane ua tus neeg sawv cev foaming.Nws yog dav siv nyob rau hauv cov kav dej, liquefied natural gas khiav kav, roj kav thiab lwm yam teb.Cov yam ntxwv yog raws li nram no:
(1) zoo flowability, los ntawm kev tswj cov mis kom haum txawvcev diameters.
(2) kev ua haujlwm kub-ua haujlwm, ua haujlwm ntevhauv 150 ℃
(3) zoo heev uas tsis muaj qhov ntsuas kub stability
