Polyester POLYOL ee CPU
Taxanaha polyester polyols waxaa inta badan loo isticmaalaa elastomers, iyo sida waafaqsan shuruudaha macaamiisha si loo hagaajiyo miisaanka kelli.Alaabooyinka hoose ee ay soo saaraan taxanahan polyols waxay leeyihiin sifooyin caabbinta xidhashada, caabbinta laalaabida, iska caabinta jeexjeexa iyo xoogga farsamada sare.
Taxanaha polyester-ka ayaa si weyn loogu isticmaalaa duurka tuurista elastomeryada poliurethane, inta badan waxaa loo isticmaalaa saxanka shaandhada poliurethane ee adag, dhejisyada, sariiraha, taarikada iyo baararka, alaabada dheriga la qaabeeyey.
