Polyester POLYOL rau CPU
Cov series polyester polyols yog tsuas yog siv nyob rau hauv elastomers, thiab raws li cov neeg yuav tsum tau los kho cov molecular hnyav.Cov khoom lag luam qis uas tsim los ntawm cov khoom siv ntawm polyols no muaj cov yam ntxwv ntawm kev hnav tsis kam, folding tsis kam, tearing tsis kam thiab siab txhua yam muaj zog.
Cov series ntawm polyester polyols yog dav siv nyob rau hauv lub teb ntawm casting polyurethane elastomers, mas siv nyob rau hauv siab hardness polyurethane sieve phaj, casters, cots, daim hlau thiab tuav, molded potting khoom.
