Product Name:Hydroxypropyl methylcellulose
English Name:Hydroxypropyl methylcellulose
CAS No.:9004-65-3
Aliases:Hypromellose, HPMC, Cellulose hydroxypropyl methyl ether, Hydroxypropyl methylcellulose ether
Molecular Formula:C6H7O2(OH)2(OCH3)x(OC3H6OH)y
Physical Properties:White or off-white powder, odorless and tasteless. Soluble in water and some organic solvents; insoluble in ethanol, ether and chloroform. The aqueous solution is transparent and stable with surface activity, and gels upon heating, reverting on cooling. It has thickening, suspending, emulsifying, film-forming and water-retention properties.
Uses:Used as thickener, suspending agent, binder and film-forming agent. Widely applied in building materials (cement mortar, gypsum), coatings, pharmaceuticals (tablet coating, sustained-release preparations), food, daily chemicals and oilfield drilling.
Technical Specifications:
Appearance: white or off-white powder.
Methoxy content: typically 19%-30%; hydroxypropoxy content: 4%-12%.
Viscosity of 2% aqueous solution at 20°C: 5-200000 mPa·s depending on grade.
pH of 1% aqueous solution: 5.0-8.0.
Loss on drying: not more than 5%.
