Polyester POLYOL KWA CPU
Mfululizo wa polyols za polyester hutumiwa hasa katika elastomers, na kulingana na mahitaji ya wateja ili kurekebisha uzito wa Masi.Bidhaa za chini zinazozalishwa na mfululizo huu wa polyols zina sifa ya upinzani wa kuvaa, upinzani wa kukunja, upinzani wa machozi na nguvu ya juu ya mitambo.
Mfululizo wa polyols ya polyester hutumiwa sana katika uwanja wa kutupwa elastomers za polyurethane, zinazotumiwa hasa katika sahani ya ungo ya ugumu wa polyurethane, casters, vitanda, sahani na baa, bidhaa za potting zilizoumbwa.
