Polyurethane polyester polyols feem ntau yog siv nyob rau hauv kev tsim cov chaw ua haujlwm hauv nruab nrab nrog:
Thermal conductivity
Yooj yim
Adhesion
Tshuaj tiv thaiv
Thaum nws los txog rau kev lag luam textile, polyester polyols tuaj yeem siv rau txheej thiab tiav daim ntaub ntawv ntawm cov ntaub, nrog rau cov cots.
Cots, yog cot rolls los yog cot tuav, yog cylindrical roj hmab los yog hluavtaws chais siv nyob rau hauv textile processing machines, xws li spinning, weaving, thiab tshuab luam ntawv.
Polyester polyols siv rau cots yog cov khoom siv zoo heev xws li hardness, tensile zog, thiab puas resistant; tshuaj tsis kam, zoo adhesion, yooj thiab thermal stability.
Lub series ntawm polyurethane raw khoom polyester cov khoom yog ib hom ntawm Polyester polyol rau CPU, feem ntau yog siv nyob rau hauv cots, hnyav-resistant cov khoom, nplaum, tawv tawv, cov thawj cov kua, composite kua nplaum thiab lwm qhov chaw ntawm polyurethane khoom.
