Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose. It contains almost methyl cellulose(MC) of all the performance, your first choice for production of high quality building materials additives.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.
*thermal insulation mortar, ceramic tile adhesive, jointing agent, stucco gypsum, plaster;
*paint thickening agent, dispersing agent and stabilizer;
*ink industry as the thickening agent, dispersing agent and stabilizer;
*plastic forming mold release agent, softener, lubricants;
*cement, gypsum secondary products;
*shampoo, detergent
Advantages:
Water soluble and thickening ability: this product is soluble in cold water, and it can form transparent sticky solution. In organic solvent of dissolved: because it contains a certain amount of hydrophobic methoxyl, this product is soluble in some organic solvent; it is also soluble in water and organic mixed solvent.
Hydroxypropyl methyl cellulose (HPMC) salt resistance: because ion and the polyelectrolytein exsist in this product, its metal salt or organic electrolyte aqueous solution is stable.
Surface activity: HPMC for daily chemical aqueous solution has the surface activity, ensuring its emulsification, protective colloid and relative stability.
Low ash content: because ion exist in this product, in preparation process we can use hot water washing for effective refinement, so its ash content is very low.
pH stability: HPMC aqueous solution viscosity in the range of pH3.0-11.0 is more stable.
Water retention effect: this product is hydrophilic and its solution has high viscosity.
Film-forming property: HPMC can generate strong pliable and transparent sheet, which has the good oil resistance to ester performance.
