Cov kab no ntawm polyols yog cov tshuaj tsw qab polyester polyols uas tau npaj los ntawm polycondensation lossis kev hloov pauv ntawm phthalic anhydride, diethylene glycol thiab lwm yam khoom siv raw.Lawv tsuas yog siv nyob rau hauv lub tshav pob ntawm tawv ua npuas ncauj thiab adhesives.Lawv muaj qhov zoo ntawm cov ntxhiab tsw, tsis muaj xim, muaj kev ua haujlwm siab, zoo heev hydrolysis stability, siab aromatic cov ntsiab lus, zoo stability thiab fluidity ntawm cov ntaub ntawv sib xyaw, Thiab cov qauv khoom tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.

Cov khoom siv ntawm polyester polyols no tuaj yeem siv dav hauv tub yees, txias cia, txau, hnub ci zog, thermal pipelines, tsev rwb thaiv tsev thiab lwm qhov chaw ntawm cov khoom ua npuas tawv tawv, qee cov khoom siv nplaum.
