Definitsioon, keemia ja tööstuslik roll — täielik juhendmaterjal koostajatele ehitus-, farmaatsia-, toidu-, isikuhooldus- ja tööstussektoris.
HPMC on vees lahustuv, mitteioonne tselluloosi eeter, mis on toodetud puidumassist või puuvillalinterist saadud loodusliku tselluloosi keemilise modifitseerimise teel. See pakub mitmeid funktsionaalseid eeliseid – vee kinnipidamine, paksendamine, kile moodustamine, sidumine ja töödeldavuse parandamine – ühes mitmekülgses koostisosas.
HPMC toodetakse puhastatud tselluloosi reageerimisel metüülkloriidi ja propüleenoksiidiga kontrollitud aluselistes tingimustes. See protsess lisab tselluloosi põhiahelasse kahte tüüpi asendusrühmi, millest igaüks mõjutab lõpptoote jõudlusprofiili erineval viisil.
Kontrollige tsellulooseetri lahustuvust, termilist geelistumiskäitumist ja pindaktiivsust.
Mõjutavad vee sidumisvõimet, viskoossuse teket ja sobivust teiste koostisosadega.
Nende kahe asendusrühma kombinatsioon ja suhe – väljendatuna metüülasenduse astmena (DS) ja hüdroksüpropüüli molaarse asendusena (MS) – määravad klassi toimivusprofiili. Viskoossus, mida mõõdetakse 2% vesilahuses Brookfieldi või Ubbelohde meetoditega, on kõige sagedamini viidatud parameeter klassi valikul, ulatudes sõltuvalt klassist alla 100 mPa·s kuni üle 200 000 mPa·s.
HPMC on mitteioonne – ühildub paljude lisandite, pindaktiivsete ainete, soolade ja pH-tingimustega. See on ka biolagunev, lõhnatu, maitsetu ning vaba loomsetest toorainetest, muutes selle sobivaks reguleeritud ja tundlikeks rakendusteks alates kuivsegumörtidest kuni farmaatsia abiainete ja toidusüsteemideni.
Järgmine tabel annab üldise tehnilise viite hüdroksüpropüülmetüültselluloosi kohta. Täpsed väärtused varieeruvad sõltuvalt toote klassist, viskoossuse tasemest, asendustüübist, osakeste suurusest, pinnatöötlusest ja testimismeetodist. See teave on mõeldud koostise viite lähtepunktina, mitte lõpliku toote spetsifikatsioonina.

LANDERCOLL HPMC on saadaval mitmes viskoossustaseme, pinnatöötluse, lahustumiskäitumise ja sihtrakenduse põhises klassi suunas. Allolev teave on mõeldud toote valiku juhendina. Lõplik klassi valik tuleb alati kinnitada koostise testimise ja otsese tehnilise arutelu kaudu meie meeskonnaga.
Hiline hüdratatsioon — lihtsam dispersioon, vähem tükke, kontrollitud lahustumine. Eelistatud kuivsegusüsteemides.
Kiirem viskoossuse areng — kiire hüdratatsioon, sobib kiiresti lahustuvateks ja otsese hüdratatsiooniga preparaatideks.
Märkus: Ülaltoodud viskoossusvahemikud on ligikaudsed viited. Tegelikud LANDERCOLL HPMC klassid tuleks valida vastavalt teie koostisele, testimismeetodile, kasutuskeskkonnale ja nõutavale dokumentatsioonile. Konkreetsete klasside soovituste saamiseks võtke ühendust meie meeskonnaga.
HPMC on multifunktsionaalne tselluloosueeter. Enamikes rakendustes pakub see korraga mitut funktsionaalset eelist. Allpool on struktureeritud ülevaade selle peamistest funktsioonidest erinevates süsteemitüüpides.
Tsemendi- ja kipsipõhistes süsteemides moodustab HPMC polümeervõrgustiku, mis füüsiliselt piirab vee liikumist. Kõrgema viskoossusega klassid ja suuremad annustasemed tagavad tugevama veepeetuse – vältides kiiret vee kadu, mittetäielikku hüdratatsiooni ja pinnapragunemist.
HPMC lahustub külmas vees, moodustades viskoosse, pseudoplastilise (nihketihenduva) lahuse. Viskoossus väheneb segamise ajal nihke mõjul ja taastub puhkeolekus – toetades nii töödeldavust kui ka paigalseisu stabiilsust kuivsegumörtides, detergentides, isikuhooldustoodetes ja kattekihtides.
Kuivsegude ehitusmaterjalides muudab HPMC mördi siledamaks, sidusamaks ning kergemini laotatavaks, kellutavaks, kaabitsetavaks ja viimistletavaks. See on vee kinnipidamise, viskoossuse suurendamise ja määrimise koosmõju tulemus – eriti hinnatud plaadiliimides, seinapahtlites ja kipskrohvides.
Toetab voolu reguleerimist, longuskindlust, tasanduskäitumist ja pealekandmise stabiilsust. Hoiab ära mördi libisemise vertikaalsetel pindadel, aitab kaasa kontrollitud voolule isetasanduvates segudes ning säilitab stabiilse viskoossuse kattekihtides ja pesuvahendites.
HPMC moodustab pärast vee aurustumist pideva ja painduva kile – kasutatakse farmaatsiatablettide katmiseks, söödavates kiledesüsteemides, ehituskonstruktsioonide terviklikkuse tagamiseks ja valitud veepõhistes kattekihtides sideainekomponendina.
Toetab struktuurset terviklikkust tablettide tootmisel, rohelist tugevust keraamikas ja kohesiooni kuivsegumörtides. Aitab säilitada pigmentide, täiteainete, mineraalpulbrite ja toimeainete ühtlast suspensiooni kattekihtides, detergentides ja farmaatsiasüsteemides.
HPMC klassi valik peaks alati algama rakendusest. Plaadiliimi jaoks optimeeritud klass ei pruugi tingimata hästi toimida detergentides, isikliku hügieeni toodetes ega farmaatsiasüsteemides. Allolev tabel annab struktureeritud viite tavaliste rakenduste ja klasside sobitamiseks.

These dosage ranges are general starting points. Adjust based on testing results under your specific formulation, raw materials, and application conditions.
Construction is the largest and most established application area for HPMC globally — a critical additive for water retention, workability, open time, and anti-sag performance.
In drymix mortar systems, HPMC functions simultaneously as a water-retaining agent, rheology modifier, and workability enhancer. Without HPMC, cement-based and gypsum-based mortars tend to lose water too quickly to the substrate, resulting in poor hydration, weak bond strength, surface cracking, and difficult application.
Water retention, open time extension, anti-slip behavior, and troweling feel. High to extra-high viscosity grades, 0.2%–0.5% dosage. Surface-treated grades commonly preferred.
Scraping smoothness, water retention, surface finish quality. Medium to high viscosity, 0.2%–0.5% dosage.
Controlled water retention without over-retarding set time. Smooth spreading, consistent texture, reduced surface defects. Medium to high viscosity grades.
Cement render, masonry mortar, self-leveling compounds, EIFS/ETICS, waterproof mortar, repair mortar, insulation mortar, joint fillers.
Koduhooldus ja pesuvahendid
As a non-ionic polymer, HPMC is compatible with anionic and non-ionic surfactant systems commonly used in cleaning products. It builds smooth, stable viscosity that improves product appearance, pourability, and consumer perception — while helping maintain uniform suspension of insoluble components.
Typical Applications
Isiklik hügieen
In personal care systems, HPMC functions as a viscosity modifier, texture enhancer, and formulation stabilizer. It is water-soluble, non-ionic, and free from animal-derived raw materials — making it suitable for a wide range of rinse-off and leave-on products where smooth, consistent texture and formulation stability across temperature and storage conditions are required.
Typical Applications
Suitable pharmaceutical grades of HPMC — referred to as Hypromellose in pharmacopoeial standards — are widely used as functional excipients in solid dosage forms, film coatings, and controlled-release systems. HPMC is recognized in the USP/NF, Ph. Eur., and JP pharmacopoeias.
Only grades manufactured and tested to pharmacopoeial standards should be used. Grade selection is based on viscosity grade, substitution type, regulatory compliance, and documentation requirements.

HPMC (CAS 9004-65-3) is used as a multifunctional cellulose ether additive across many industries. Its primary functions include water retention, thickening, workability improvement, film formation, binding, and formulation stabilization. Most widely used in drymix construction materials, and also in detergents, personal care, pharmaceutical excipients, food systems (E464), coatings, ceramics, and specialty industrial applications.
In tile adhesive, HPMC improves water retention to support cement hydration, extends open time to give installers more working time, provides anti-slip behavior to prevent tiles from sliding on vertical surfaces, and improves troweling feel and application consistency. High to extra-high viscosity grades are typically used, at dosages of 0.2%–0.5% of the dry mix weight.
Tile adhesive commonly uses high to extra-high viscosity HPMC, typically in the range of 50,000–200,000 mPa·s (measured at 2% aqueous solution). The exact viscosity grade depends on the formulation type, tile size and weight, required open time, anti-slip performance target, and application conditions. Final grade selection should be confirmed through formulation testing.
The typical reference dosage for HPMC in tile adhesive is 0.2%–0.5% by weight of the dry mix. This range is widely referenced in the drymix mortar industry as a starting point. However, the optimal dosage depends on the specific formulation, cement type, filler quality, target open time, water retention requirement, and application conditions. Final dosage must be confirmed through laboratory and field testing.
In wall putty and skim coat, HPMC improves water retention to prevent rapid drying, enhances scraping smoothness and surface finish quality, improves spreading behavior and workability, and helps maintain consistent product texture during application. Medium to high viscosity grades are typically used at dosages of 0.2%–0.5%.
HPMC uses hydroxypropyl groups while HEMC uses hydroxyethyl groups on the cellulose backbone, affecting water retention profile, dissolution behavior, and performance in specific applications. Both are used in tile adhesive, wall putty, and plaster. HPMC is more widely used across multiple industries including pharma, food, and personal care, while HEMC/MHEC is particularly established in European drymix construction markets.
