Polima ya aina ya polyether/TDI
Bidhaa hizo zina upinzani mzuri wa kuvaa, upinzani wa maji, upinzani wa mold, mali bora ya mitambo, na rangi inaweza kuongezwa ili kurekebisha rangi.Inatumika kutengeneza bidhaa za polyurethane kama vile fimbo ya mpira, gurudumu la mpira, sahani, mipako ya mpira na sehemu tofauti.
