Hydroxypropyl methylcellulose is a non-toxic, odorless, calorie-free white powder. HPMC is almost insoluble in absolute ethanol, ether and acetone. It can be dissolved in water, and the aqueous solution is quite stable at normal temperature. It has excellent dispersibility, adhesion, thickening, emulsifying, water retention and film-forming properties, as well as impermeability to grease. Widely used in construction, building materials, dispersible coatings, etc. For example, if it is added in the coating industry, it can be used as a film-forming agent and thickener, which is a great help to improve the fluidity of the coating.
HPMC can be used as water or water used for organic solvent coating, excellent film forming and viscosity. It has good barrier, increasing compressive strength and reducing debris. It also can be used as a coating of organic solvent to form a solid with good adhesive film. It's a good masking role of smell.
we are HPMC manufacturers,if you want to buy HPMC ,pls contact us.
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
