Pharmacy Polymer Materials
1. Croscarmellose sodium (cross-linked CMCNa): a cross-linked copolymer of CMCNa Properties: White or off-white powder. Due to the cross-linked structure, it is insoluble in water; it swells rapidly in water to 4-8 times its original volume. The powder has good fluidity. Application: It is the mo...Read more -
Effects of HPMC on water retention, thickening and fluidity of mortar
Figure 1 shows the change of water retention rate of mortar with the content of HPMC. It can be seen from Figure 1 that when the content of HPMC is only 0.2%, the water retention rate of mortar can be significantly improved; when the content of HPMC is 0.4%, the water retention rate has reached 9...Read more -
Application of Domestic Hydroxypropyl Methyl Cellulose in Production of High Polymerization Degree of Polyvinyl Chloride
Abstract: The application of domestic hydroxypropyl methylcellulose instead of imported one to the production of PVC with high polymerization degree was introduced． The effects of two kinds of hydroxypropyl methylcellulose on the properties of PVC with high polymerization degree were investigate...Read more -
Redispersible polymer powder of dry mix mortar additives series
n the actual environment of the market, various types of latex powders can be described as dazzling. As a result, if the user does not have his own professional technicians or testing equipment, he can only be fooled by many unscrupulous merchants in the market. At present, there are some so-call...Read more -
The role of redispersible polymer powder in dry mortar
Redispersible polymer powders are dispersions of polymer emulsions after spray drying. With its promotion and application, the performance of traditional building materials has been greatly improved, and the bonding strength and cohesion of the materials have been improved. Redispersible latex po...Read more -
Application of dispersible polymer powder in building materials industry

The role of dispersible polymer powder in putty powder
1. Putty is used as a material for pretreatment of the surface to be coated in architectural coatings Putty is a thin layer of leveling mortar. Putty is scraped on the surface of rough substrates (such as concrete, leveling mortar, gypsum board, etc.) Make the exterior wall paint layer smooth and...Read more -
Common applications of dispersible polymer powders
The rubber powder is made of high temperature, high pressure, spray drying and homopolymerization with a variety of active-enhancing micropowders, which can significantly improve the bonding ability and tensile strength of the mortar. , outstanding heat aging performance, simple ingredients, easy...Read more -
Application of Redispersible Polymer Powder in Mortar System
Dispersible polymer powder and other inorganic binders (such as cement, slaked lime, gypsum, etc.) and various aggregates, fillers and other additives (such as methyl hydroxypropyl cellulose ether, starch ether, lignocellulose, hydrophobic Agents, etc.) are physically mixed to make dry-mixed mort...Read more -
The role and precautions of redispersible latex powder
Redispersible latex powder is a powder dispersion obtained by spray drying of modified polymer emulsion. It has good dispersibility and can be re-emulsified into a stable polymer emulsion after adding water. Its chemical properties are exactly the same as the initial emulsion. Therefore, In order...Read more -
Why add hydroxypropyl methylcellulose (HPMC) to gypsum-based mortar
In cement mortar and gypsum-based slurry, hydroxypropyl methylcellulose mainly plays the role of water retention and thickening, which can effectively improve the cohesion and sag resistance of the slurry. Factors such as air temperature, temperature and wind pressure will affect the evaporation ...Read more -
Properties of Hydroxyethyl Cellulose
Hydroxyethyl cellulose It is a non-ionic water-soluble polymer, white or slightly yellow, easy-flowing powder, odorless and tasteless, soluble in both cold water and hot water, and the dissolution rate increases with the increase of temperature. Insoluble in organic solvents. Properties of hydrox...Read more
