Hydroxyethyl methyl cellulose(HEMC) ndi polima wosungunuka m'madzi womwe umagwiritsidwa ntchito ngati thickener, gelling agent, ndi zomatira. Iwo akalandira ndi mankhwala anachita wamethyl cellulosendi vinyl chloride mowa. HEMC ili ndi kusungunuka kwabwino komanso kuyenda bwino, ndipo imagwiritsidwa ntchito kwambiri m'magawo monga zokutira zokhala ndi madzi, zida zomangira, nsalu, zinthu zosamalira anthu, komanso chakudya.
Mu zokutira zokhala ndi madzi, HEMC imatha kutenga nawo gawo pakukulitsa ndi kuwongolera kukhuthala, kuwongolera kuyenda ndi kuyanika kwa zokutira, kuti zikhale zosavuta kugwiritsa ntchito ndikuyika. Mu zomangira,MHEC thickeneramagwiritsidwa ntchito mu mankhwala monga youma matope osakaniza, simenti matope, ceramic matailosi zomatira, etc. Ikhoza kuonjezera adhesion ake, kusintha flowability, ndi kusintha kukana madzi ndi durability zinthu.
