Polycarbonate Diols (PCDs)
Lwm cov chav kawm nthuav dav ntawm polyols siv rau thermoplastic polyurethane ntau lawm yog Polycarbonate diols. Feem ntau siv los tsim cov polyurethanes uas sib txuas cov carbonate txuas rau kev ua tau zoo dua. Polycarbonate-polyurethanes tuaj yeem tsim los ntawm kev siv cov polycarbonate-raws li polyurethane prepolymers.
Lub polycarbonate-raws li polyurethane prepolymer yog ib qho derivative ntawm cov sib txuas polycarbonate diol nyob rau hauv uas tag nrho cov polyol hydroxyl (OH) kawg pab pawg tau reacted nrog ib tug isocyanate tawm hauv isocyanate pawg (NCO) ntawm lub termini es tsis txhob hydroxyl.
Thaum piv rau polycaprolactone thiab PTMEG-raws li polyurethanes, PU elastomers raws li PC-PU prepolymers nthuav tawm:
Durability heev
Cov tshuaj tiv thaiv siab dua
Txhim kho hydrolytic stability
Ntau dua thermal kuj
Zoo abrasion kuj, thiab
Superior mechanical zog
