hydroxypropylmethyl cellulose HPMC chemical
Hydroxypropyl methyl cellulose HPMC cps 9004-65-3
Manufacture HPMC Chemicals Hydroxypropyl Methyl Cellulose
Construction Trade Hydroxypropyl Methhyl Cellulose HPMC As Chemical Additives In Mortar, Cement Plaster, Putty, Tile Adhesive
HPMC is odorless, tasteless,non-toxic cellulose ethers producted from natural high molecular cellulose through series of chemical processing and achieved.With good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protetive colloid properties of surface activity and maintain moisture function properties ect.To meet the needs of environmental protection, Our product with high water retention, dispersion, good fineness, good work ability, easy dissolution characteristics.It suitable for dry mortar building, both inside and outside wall putty powder milk (cream), adhesives, caulks, interface agents, coatings, self-leveling agent of new building materials.

Product Properties:
1. Appearance: White or similar white powder, odorless and tasteless.
2. Particle size: 100 mesh pass rate is more than 98.5%, 80 mesh pass rate is more than 100%.
3. Carbonization temperature: 280-300 C.
4. Visual density: 0.25-0.70g/ (usually 0.5g/ or so), specific gravity 1.26-1.31.
5. Discoloration temperature: 190-200 C.
6. Surface tension: 20% aqueous solution is 42-56 dyn/cm.
7. Solubility: Soluble in water and some organic solvents, such as appropriate proportion of ethanol/water, propanol/water, dichloroethane, etc. Aqueous solution has surface activity, high transparency and stable performance. The gel temperature of different specifications of products is different, which is the thermal gelation property of HPMC. The solubility varies with the viscosity. The lower the viscosity, the greater the solubility. The properties of HPMC with different specifications are different. The solubility of HPMC in water is not affected by the PH value.
8. HPMC decreased with the decrease of methoxy group, the gel point increased, the solubility of water decreased, and the surface activity also decreased.
9. HPMC also has the characteristics of thickening ability, salt removal, low ash content, PH stability, water retention, dimensional stability, excellent film-forming ability, extensive enzyme resistance, dispersibility and adhesion.
