POLYESTER POLYOL rau CPU
Cov polyester polyols nrog molecular hnyav ntawm 500-4000G / Mol muaj qhov zoo ntawm chromaticity tsawg thiab kev ua haujlwm ruaj khov.Lub TPU ua los ntawm polyester polyols muaj qhov zoo ntawm ruaj khov viscosity, txiav yooj yim, zoo heev mechanical zog, siab hnav tsis kam, tsim kua muag thiab ceev molding, thiab tuaj yeem kho qhov hnyav molecular raws li cov neeg siv khoom.
Cov khoom siv ntawm polyester polyols no tuaj yeem siv dav hauv TPU elastomer kub yaj nplaum, cov khoom siv khau, yeeb nkab, zaj duab xis, cable sheath, conveyor siv thiab lwm yam khoom siv polyurethane.
