Dissolution in organic solvent: because it contains a certain amount of hydrophobic methoxy, the product can be dissolved in some organic solvents, or in the solvent mixed with water and organic substances.
Salt resistance: As this product is a non-ionic and non polymeric electrolyte, it is relatively stable in the aqueous solution of metal salts or organic electrolytes
Surface activity: The aqueous solution of this product has surface activity, which enables it to have emulsifying effect, protect colloid and relative stability.
Low ash content: As this product is non-ionic, it can be effectively refined by washing with hot water during preparation, so its ash content is very low.
Water retention function: Because this product is hydrophilic and its aqueous solution is high viscosity. It is added to mortar, gypsum, paint, etc. to maintain high water retention in products.
Q:What is HPMC?
A:HPMC stands for Hydroxypropyl Methyl Cellulose, which is a non-ionic cellulose ether widely used in various industries such as construction, coatings, pharmaceuticals, food, and cosmetics .
Q:What are the main applications of HPMC?
A:HPMC is used in building materials like mortar and plaster, as a thickener in coatings, as a binder in pharmaceuticals, as a food additive for stability and texture, and in cosmetics for emulsion stabilization among other applications.
Q:How is HPMC classified based on its viscosity?
A:HPMC is classified based on its viscosity, ranging from low viscosity for applications like self-leveling mortar to high viscosity for use in tile adhesives and crack-resistant mortars.
Q:What are the differences between quick-dissolving and thermal-dissolving HPMC?
A:Quick-dissolving HPMC disperses rapidly in cold water and forms a viscous solution over time, while thermal-dissolving HPMC requires hot water for dispersion.
Q:Is HPMC stable under different pH conditions?
A:HPMC is stable within a wide pH range, typically between 5.0 and 8.0, making it versatile for various applications.
