98% Purity Hydroxypropyl Methyl Cellulose (Hpmc) Cas No: 9004-65-3

Methyl cellulose (MC), hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials-cellulose as raw material, through a series of chemical processing and obtained non-ionic cellulose ethers.Methyl cellulose (MC), hydroxypropyl methyl cellulose ether (HPMC) is an odorless, tasteless, non-toxic white powder, can be dissolved in cold water, forming a transparent viscous solution, with thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelling, surface activity, retention of water and protective colloid and other characteristics.Methyl cellulose (MC) and hydroxypropyl methyl cellulose (HPMC) can be used in building materials, coatings, synthetic resins, ceramics, pharmaceuticals, food, Fang Wei, agriculture, cosmetic mouth and tobacco industries.

Hydroxypropyl methylcellulose is a non-ionic cellulose ether prepared from refined cotton as the main raw material and processed by a series of etherification reaction.Its main performance is as follows:

1, HPMC is a white or slightly yellowish powder, and odorless, tasteless, non-toxic.
2, HPMC instant cold water soluble type can be dissolved in cold water, forming a transparent viscous solution: because it contains a certain amount of hydrophobic methoxy, so this product can be dissolved in some organic solvents.
3, the viscosity of HPMC aqueous solution in the PH3. 0-10. 0 range are relatively stable, less than 3 or greater than 10, the viscosity will be greatly reduced.
4,HPMC aqueous solution has a surface activity, it has emulsification, protective colloid and relative stability.
5,Since HPMC non-ionic, hot water can be washed in the preparation process, effectively refined, so its ash content is very low.
6,Since HPMC nonionic and non-polymeric electrolyte, therefore, it is relatively stable in an aqueous solution of a metal salt or an organic electrolyte.
7,Because HPMC is hydrophilic, its aqueous solution is high viscosity, it is added to the mortar, plaster, paint, etc., to maintain high water retention in the product.
8,Adding HPMC can reduce the friction coefficient and improve the construction of lubricationi

Main uses:
Construction industry
1.Cement mortar: improve the dispersion of cement sand mortar greatly improve plasticity and water retention, to prevent cracks, can enhance the strength of cement.
2.Tile cement: improve, suppress the plasticity of the tile mortar, water retention, improve the bonding strength of the tiles, to prevent chalking.
3.Asbestos and other refractory coating: as a suspension security agent, fluidity improving agent, but also improve the bonding strength of the substrate.
4. Gypsum coagulation slurry: improve water retention and workability, improve the adhesion to the substrate.
5.Jointed cement is added to jointed cement used in plasterboard to improve mobility and water retention.
6.Latex Putties: improve the flowability and water retention of Putties based on gum latex.
7.Stucco: as a paste in natural products, can improve the water retention, improve the adhesion with the substrate.
8.Paint: as a plasticizer of latex paint, improve the operation performance of paint and Putty powder and improve the liquidity of the role.
9.Spray paint: to prevent cement or latex system, spray paint filler subsidence and improve liquidity and spray beam graphics have good results.
10.Cement, gypsum secondary products: as a cement asbestos and other hydraulic substances extrusion molding binder use, improve liquidity, can get a uniform molded product.
11.Fiber wall: due to the anti-bacterial action against the enzyme, as a binder sand wall is effective.
12.Other: can be used as a thin mortar mortar and mortar operations (PC version) of the role of the bubble retention agent.


Product features:
1.Hydroxypropyl methylcellulose soluble in cold water,hot water will be difficult to dissolve.Butits gelling temperature in hot water is significantly higher than methyl cellulose.
