Lokacin zabar tsakanin HEC da HPMC, yi la'akari da waɗannan abubuwan:
- Bukatun Danko: Domin yawan danko da kuma buƙatar samar da fim, HEC ya fi dacewa.
- Bukatun narkewa: Idan ruwan sanyi yana da mahimmanci, HPMC ya dace.
- Daidaiton pH: Don aikace-aikacen da ke buƙatar kwanciyar hankali a fadin kewayon pH mai faɗi, HEC ya dace.
- Takamaiman Kuɗi: Idan kasafin kuɗi abin damuwa ne, HPMC tana ba da mafita mafi inganci.
A ƙarshe, duka HEC da HPMC suna ba da fa'idodi daban-daban dangane da takamaiman buƙatun aikace-aikacen. Kimanta abubuwa kamar ɗanko, narkewa, kwanciyar hankali na pH, halayen samar da fim, da farashi zai jagoranci zaɓin mafi kyawun abubuwan da aka samo daga cellulose don ingantaccen aiki.
