HPMC is a highly pure cotton cellulose as raw material, under alkaline conditions by special etherification and preparation.White or whitish powder.
HPMC decreases with the decrease of methoxide content, increase of gel point, decrease of water solubility and decrease of surface activity.HPMC has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film forming, and a wide range of enzyme resistance, dispersion and adhesion.
Therefore, for cement and plaster based motors, will be your best choice. It's white or off-white powder ,non-toxic tasteless, and readily soluble in hot or cold water.
HPMC also used for ceramics, tobaccos and detergents, etc.
Redispersible Polymer powder(ordinary type) is composed of a special polymers made of powder adhesive after spray drying. this powder is contact with water can be dispersed again in soon after forming emulsion, and with the nature of the same as the initial emulsion, namely the film can be formed af
Hydroxypropyl Methyl Cellulose (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 re
