Hydroxypropyl methyl cellulose is white or off-white powder. It is mainly used as a dispersant in the production of PVC. In addition, it is used as a thickener, stabilizer, emulsifier, and film-forming agent in the production of other petrochemicals, coatings, building materials, paint removers, papermaking, and cosmetics. Hydroxypropyl methyl cellulose (HPMC) is widely used in building materials, coatings, synthetic resin, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries.Methyl cellulose is a non - ionic cellulose ether made from natural polymer cellulose through a series of chemical processing.Methyl cellulose is a odorless, tasteless, non-toxic white powder that dissolves in cold water to form a clear, viscous solution.It has the properties of thickening, adhesion, dispersion, emulsification, film forming, suspension, adsorption, gelation, surface activity, moisture retention and colloid protection.
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
