The transparency and performance of hydroxypropyl methyl cellulose are relatively stable. The performance requirements of hydroxypropyl methyl cellulose have relatively different requirements. For example, what is the solubility of hydroxypropyl methyl cellulose products?

When it comes to redispersible latex powder, we can think of its film-forming effect and adhesion, so is it really all Are they all film-forming?
Redispersible latex powder is a polymer emulsion through spray drying, freeze drying or spin flash evaporation

External thermal insulation system-choosing an appropriate amount of HPMC can maximize the bonding strength and smooth construction of the bonding mortar, and improve work efficiency.

Tile adhesive-HPMC’s good water retention, enhanced adhesion,

Hydroxypropyl methyl cellulose is a propylene glycol ether of methyl cellulose, in which both hydroxypropyl and methyl are combined with the anhydrous glucose ring of cellulose by ether linkages. It is a non-ionic cellulose ether and is easily dispersed in In cold water, the solution can form a thin film after drying. The aqueous solution is characterized by a pseudoplastic fluid and has the effect of mixing. After heating, a reversible thermal gel is formed.

The first step in the production of redispersible polymer powders is the production of polymer dispersions, also known as emulsions or latexes. SLEO are based on water-based polymer dispersions and do not contain any solvents.

The viscosity of HPMC is inversely proportional to temperature, that is, the viscosity increases as the temperature decreases. We usually say that the viscosity of a product refers to the result of testing its 2% aqueous solution at a temperature of 20 degrees Celsius.

After the PVA powder is mixed with other powders, the paste slurry is formed by adding water. After evaporation, the structure of inorganic and organic binder is formed, the brittle rigid skeleton of the water rigid material,

MC is methyl cellulose, which is made into cellulose ether by a series of reactions after the refined cotton is treated with alkali, using methyl chloride as the etherification agent. Generally, the degree of substitution is 1.6~2.0, and the solubility varies with the degree of substitution. Belongs to non-ionic cellulose ether.
