POLYESTER POLYOL YA CPU
Ma polyester polyols omwe ali ndi kulemera kwa maselo a 500-4000G / Mol ali ndi ubwino wa chromaticity yochepa komanso ntchito yokhazikika.TPU yopangidwa kuchokera ku polyester polyols ili ndi ubwino wa kukhuthala kokhazikika, kudula kosavuta, mphamvu zamakina, kukana kuvala kwambiri, kukana misozi ndi kuumba mofulumira, ndipo imatha kusintha kulemera kwa maselo malinga ndi zofuna za makasitomala.
Mndandanda wa polyester polyols angagwiritsidwe ntchito ankagwiritsa TPU elastomer otentha Sungunulani zomatira, zinthu nsapato, chitoliro, filimu, chingwe m'chimake, conveyor lamba ndi mankhwala ena polyurethane.
