I-HPMC (Hydroxypropyl Methyl Cellulose) iyi-ether ye-cellulose ether esetshenziswa kakhulu ezimbonini ezahlukahlukene. Itholakala ku-cellulose yemvelo futhi iguqulwe ukuze iba nezakhiwo ezithile ezenza ilungele izinhlelo zokusebenza eziningi. Lo mbhalo uzohlola izici ezibalulekile, izinzuzo, nokusetshenziswa kwe-HPMC. I-HPMC yi-polymer encibilikayo emanzini etholakala ku-pulp yokhuni noma imicu yokotini. Ikhiqizwa ngokwelapha i-cellulose nge-propylene oxide ne-methyl chloride, okuholele ekufakweni kwamaqembu e-hydroxyl ngamaqembu e-hydroxypropyl nama-methyl. Lokhu kuguqulwa kwamakhemikhali kuthuthukisa ukuncibilika kwayo, ukuzinza okushisayo, kanye nezakhiwo zokwakha amafilimu.
