Hydroxypropyl methylcellulose (HPMC) is a kind of odorless, tasteless, non-toxic white powder. After fully dissolved in water, HPMC will form a transparent viscous colloid.The main raw materials of hydroxypropyl methylcellulose (HPMC) are refined cotton, methyl chloride, propylene oxide, and other raw materials and chemicals, such as caustic soda, acid, toluene, isopropanol.

Cement mortar: improve the dispersibility of cement and sand, greatly improve the plasticity and water retention of mortar, and improve the strength of cement.
HPMC used in Tile adhesive: to improve the plasticity, water retention and glue relay of ceramic tile mortar, to prevent powder.
Coating of fireproof materials such as asbestos: as suspension agent, fluidity improver, and improved adhesive relay on basement.
Gypsum plaster: improve the water retention and processing, and improve the adhesion of the base.

In the application of building materials, hydroxypropyl methylcellulose has its unique properties from mixing to dispersion to construction, as follows:
Firstly, compounding and configuration

The broad prospects of hydroxypropyl methylcellulose in the construction industry cannot be questioned. Its excellent thickening performance and water retention performance make its application in the construction industry not to be ignored. Now let’s talk about the viscosity characteristics of the aqueous solution of hydroxypropyl methylcellulose:

1.Cement mortar: HPMC improves the dispersibility of cement-sand, greatly improves the plasticity and water retention of the mortar, has an effect on preventing cracks, and can enhance the strength of cement.
2. Tile cement: HPMC improves the plasticity and water retention of the pressed tile mortar, improves the adhesive force of the tile, and prevents chalking.
3. Coating of asbestos and other refractory materials: HPMC is used as a suspension agent, fluidity improver, and also improves the adhesion to the substrate.

Redispersible latex powder is a powdery dispersion made of modified polymer polymer emulsion by spray drying. It has good dispersibility and can be re-emulsified into a stable polymer emulsion after adding water. The performance is exactly the same as the initial emulsion. Therefore, it becomes possible to produce high-quality dry-mixed mortar, thereby improving the properties of the mortar.

HPMC is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protective colloid properties of surface activity and maintain moisture function properties ect.

Cellulose HPMC is widely used in construction materials, coatings, synthetic resins, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries. HPMC can be divided into construction grade, food grade and medical grade according to its usage.

Hydroxypropyl Methyl Cellulose is a natural polymer cellulose as raw material, made of a series of chemical processing and non-ionic cellulose ether. They are an odorless, tasteless non-toxic white powder in cold water swelling into a clear or slightly muddy colloid solution.
