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 production 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.
HPMC is a natural polymer cellulose made by a series of chemical treatments . Water-soluble white powder . It has thickened , adhesion , dispersion , emulsification , film formation , suspension , adsorption , gel and protective colloid surface activity , and retains moisture and other characteristics .
Industrial-grade hydroxypropyl methyl cellulose used in mortar is distinguished by viscosity. Generally, the following types are commonly used Low viscosity: 400 is mainly used for self-leveling mortar. Reason: low viscosity, good leveling, high mortar density. Medium and low viscosity: 20000-400000
Hydroxypropyl methyl cellulose ether-HPMC, as an auxiliary additive widely used in the field of building materials, is mainly used for water retention, thickening and improving the workability of the finish product. Water retention rate is often one of the core indicators for selecting high-quality
