EPT Grade HPMC Cellulose Ethers
Chemical PowEPTC1 C2 Tile Glue EPT Mortar Additive Thickener Cellulose Ether HPMC
HPMC – Hydroxypropyl methyl cellulose
HS Code: 3912, 3900
CAS: 9004-65-three
EPT Hydroxypropyl Methyl Cellulose (HPMC) is a nonionic cellulose ether polymer with diverse chemical homes dependent on the diverse diploma of modification and substitution of the substituent teams. It is odorless, tasteless, non-toXiHu (West Lake) Dis.c cellulose ethers made from normal large molecular cellulose via collection of chemical processing and reached. It is white powEPTwith very good water solubility. It has thickening, adhesion, dispersing, emulsifying, movie, suspended, adsorption, gel, and protective colloid properties of surface exercise and maintains humidity purpose homes etc. Primarily employed in construction materials, coatings business, synthetic resin, ceramic industry, textile, agriculture, everyday chemical and other EPT.
HPMC Molecular Formula:
Note: R=degree of polymerization, R=H or CH3 or CH2CHOHCH3

HPMC Properties
one. Carbonization temperature: 280-three hundred deg C
two. Density: 370-380g/l
three. Surface area stress: 2% aqueous remedy is forty two-56dyn/cm
4. Solubility: soluble in h2o and some solvents, these kinds of as ethanol/water, propanol/h2o, etc. in proper proportions.
5. No ionic demand: It is non-ionic, it does not blend with metallic salts and ionic organics to form insoluble precipitates.
6. Thermal gel home: Gel will be formed when the aqueous resolution of cellulose is heated to a particular temperature, and a resolution will be soon after cooling.
7. PH price balance: it has a vast variety of pH values.
eight. Drinking water retention: It has excellent drinking water retention homes, producing the dampness not easy to drop or be absorbed also quickly by the substrate. Some EPT grades operate effectively in large temperature environments.
9. Thickening: its aqueous resolution system has the thickening property, and the consistence is associated to the viscosity of the solution employed and the variety of compound.
10. Movie development: It can be created into a clear, difficult, delicate movie with exceptional resistance to grease.
11. Adhesion: It can be employed as a binEPTfor tile adhesives, pigments, tobacco items, paper goods, coating and so forth.
12. Suspension: It can avoid the precipitation of strong particles, since the formation of sediment can be inhibited.
13. Protective colloid: It can avert little granules or particles forming a mass.
14. Emulsification: The emulsion liquid can be stabilized by lowering the area and interfacial stress and thickening the aqueous phase.
fifteen. Anti-sagging: It can improve the thixotropy of the merchandise, so that the completed solution does not slip even at considerate thickness.
16. Wetting potential: Cellulose has the house of wetting the substrate, no curling even if utilized to a EPT substrate.
17. Open up time: It can increase the hardening time of the solution, make the raw resources totally hydrated, and enhance the tensile energy and fleXiHu (West Lake) Dis.bility of the merchandise.
HPMC Application
one. Binder: Employed as a thickener and binEPTin the adhesive formulation.
two. Ceramic: provides lubricity, drinking water retention and increases the first toughness of the ceramic embryo.
3. Developing supplies: miXiHu (West Lake) Dis.ng into cement, so that cement mortar, plaster and gypsum ingredients have water retention properties and increase their workability.
4. Cosmetics: Regulate rheology to give the product the rigEPT viscosity, emulsification, steadiness, lubricity and foam security, and surfactant compatibility.
five. Leather: It is employed as a thickener and h2o reXiHu (West Lake) Dis.Hu (West Lake) Dis. agent for leather-based surface protective rubber when it is processed and dried in the course of leather processing.
six. LaEPT coating: as a protective colloid, thickener and pigment dispersant
seven. Paint stripper: Conducive to the compatibility of h2o and natural and organic solvents, thickener in blade coating and rinse-off paint remover
8. Paper goods: film forming agent for area sizing or oil repellent coatings.
9. Plywood: Modifying the rheology of the binder
10. Various resins and rubbers: fiber reinforced plastic molding release agent, drinking water dependent coating emulsifiers, thickeners and stabilizers.
eleven. Textiles: as a textile sizing material, thickeners and stabilizers in printing paste or laEPT paints.
