Polyester polyol kwa CPU
Polyester polyols mfululizo hutumiwa hasa katika elastomers, na kulingana na mahitaji ya wateja kurekebisha uzito wa Masi. Bidhaa za chini zinazozalishwa na safu hii ya polyols zina sifa za upinzani wa kuvaa, upinzani wa kukunja, upinzani wa kubomoa na nguvu kubwa ya mitambo.
Mfululizo wa polyols za polyester hutumiwa sana katika uwanja wa elastomers za polyurethane, hutumika sana katika sahani ya ugumu wa ugumu wa polyurethane, wahusika, vifaa, sahani na baa, bidhaa zilizowekwa ndani.
