HPMC 99.9% Hydroxypropyl Methyl Cellulose

Hydroxypropyl methylcellulose is the propylene glycol ether of methylcellulose, in which both the hydroxypropyl and methyl groups are combined with the anhydrous glucose ring of cellulose through ether bonds. It is a white to grayish-white cellulose powder or granule, and has similar properties to methylcellulose, being soluble in cold water but insoluble in hot water.

Description

Hydroxypropyl MethylCellulose (HPMC) are widely used in construction, pharmaceutical,food, cosmetic, detergent, paints, as thickener, emulsifier, film-former, binder, dispersing agent, protective colloids.We can provide the regular grade HPMC, we also can provide modified HPMC according to customer requirements. After modified and surface treatment, we can get the goods which is dispersed in water quickly, lengthen open time, anti-sagging, etc.

Typical Applications of HPMC:

Tile Adhesive

Good water retention: prolonged opening time will make tiling more efficient.

Improved adhesion and sliding resistance: especially for heavy tiles.

Better workability: lubricity and plasticity of plaster is ensured, mortar can be applied easier and quicker.

Cement Plaster / Dry mix mortar

Easy dry mix formula due to cold water solubility: lump formation can be easily avoided, ideal for heavy tiles.

Good water retention: prevention of fluid loss to the substrates, the appropriate water content is kept in mixture which guarantees longer concreting time.

Increased water demand: increased open time, expanded spry area and more economical formulation.

Easier spreading and improved sagging resistance due to improved consistency.

Wall putty

Water retention: maximized water content in slurry.

Anti-sagging: when spreading a thicker coat corrugation can be avoided.

Increased mortar yield: depending on the weight of the dry mixture and appropriate formulation ,HPMC can increase the mortar volume.
