Hydroxypropyl methylcellulose imapangidwa kuchokera ku cellulose yoyera kwambiri ya thonje kudzera mu etherification yapadera pansi pa mikhalidwe ya alkaline, ndipo njira yonseyi imamalizidwa motsogozedwa ndi automatic. Sisungunuka mu ether, acetone ndi absolute ethanol, ndipo imakula kukhala yankho loyera kapena lamtambo pang'ono la colloidal m'madzi ozizira. Yankho lamadzi lili ndi ntchito pamwamba, lowonekera bwino komanso lokhazikika. Lingagwiritsidwe ntchito ngati matailosi omatira, marble, kukongoletsa pulasitiki, kulimbitsa phala, komanso lingachepetse kuchuluka kwa simenti. Mphamvu yosunga madzi ya hydroxypropyl methyl fiber imaletsa matope kuti asasweke chifukwa cha kuumitsa mwachangu mutagwiritsa ntchito, ndipo imawonjezera mphamvu pambuyo pouma.
Pamene kuchuluka kwa methoxyl kumachepa, mfundo ya gel imawonjezeka, kusungunuka kwa madzi kumachepa, ndipo ntchito ya pamwamba imachepanso. Chogulitsachi chili ndi mawonekedwe a kukhuthala, kukana mchere, ufa wochepa wa phulusa, kukhazikika kwa pH, kusunga madzi, kukhazikika kwa mawonekedwe, kupanga filimu yabwino kwambiri, komanso kukana ma enzyme osiyanasiyana, kufalikira ndi kugwirizana.
Amagwiritsidwa ntchito ngati chokhuthala, chosungunula ndi chokhazikika mumakampani opanga utoto, ndipo amagwirizana bwino ndi madzi kapena zinthu zosungunula zachilengedwe. Monga chochotsera utoto. Amagwiritsidwa ntchito ngati chokhuthala, chosungunula ndi chokhazikika mumakampani opanga inki, ndipo amagwirizana bwino ndi zinthu zosungunula zachilengedwe zamadzi kapena zinthu zosungunula zachilengedwe. Chogulitsachi chimagwiritsidwanso ntchito kwambiri m'makampani opanga zikopa, mapepala, kusunga zipatso ndi ndiwo zamasamba komanso mafakitale opanga nsalu.
