HPMC is odorless, tasteless,non-toxic cellulose ethers producted 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 protetive colloid properties of surface activity and maintain moisture function properties ect.

Hydroxypropyl Methylcellulose (HPMC) is a non-ionic ,water souble cellulose ether that form films, water-retentaion,stability, adhesiveness, especially widely used for construction materials because it is choosen to enhance adhesion, water retention, and lubricity, shrink and crack resistance. Modified OV-CEL cellulose eathers improve on the slippage, brittle resistance resistance to pressure and tensile sex. Therefore, for cement and plaster based motars, Modified OV-CEL will be your best choice. It's white or off-white powder , non-toxic tasteless,and readily soluble in hot or cold water.
OV-CELL HPMC also used for cersmics,tobaccos and detergents,etc.
