Polyester Polyol rau CPU
Cov koob polyesliv Polyols yog siv hauv Elastomers, thiab raws li cov neeg siv khoom yuav tsum kho cov kev ua haujlwm molecular. Cov khoom siv hauv nqes dej uas tsim los ntawm cov lej polycs muaj cov yam ntxwv ntawm kev hnav tsis kam, folding ua kom tsis kam, muaj zog ua kom muaj zog.
Cov koob polyeslivkas tau siv dav hauv teb ntawm cam khwb cia Polyurethane elasteane
