Case Polyether Polyol SE -220A yog dab tsi?

Case polyether polyol SE-220A yog hom polymer polyether diol pib los ntawm propylene glycol nrog qhov hnyav ntawm 2000. SE-220A muaj ntau yam kev siv, suav nrog:

Kev tsim cov sealants thiab potting compounds
Kev tsim cov adhesives
Tsim cov elastomers (piv txwv li, lub log tsheb, roj hmab rollers)

Cov khoom muaj ib tug functionality ntawm 2, txhais tau tias nws muaj ob reactive hydroxyl pawg ib molecule. Nws ruaj khov ntawm qhov kub thiab txias, tab sis tuaj yeem ua rau oxidation ntawm qhov kub thiab txias. Rau kev khaws cia, nws yuav tsum tau khaws cia ntawm qhov kub thiab txias hauv qhov chaw txias, qhuav, nrog lub ntim ntim kom tsis txhob ya raws qhov nkag. Yuav tsum tsis txhob raug tshav kub thiab qhib nplaim taws. Lub sijhawm khaws cia yog 12 lub hlis.
