Hydroxypropyl methylcellulose is propylene glycol ether of methyl cellulose, hydroxypropyl and methyl combine with anhydrous glucose ring by ether bond.It is white or pale white cellulose powder or particles. The characteristics of cold water dissolution and hot water insoluble are similar with methyl cellulose. Solubility in organic solvents is superior than water soluble, can be dissolved in anhydrous methanol and ethanol solution, also soluble in chlorinated hydrocarbons and ketones in organic solvents. Soluble in water, its water solution has a surface activity, the formation of the film after drying, heated and cooled, in turn, from the reversible conversion of sol to gel. Can be used alone in the cold drink, also can be used with other emulsifier, stabilizer. To cold drink, the maximum amount is 1%. Hydroxypropyl methyl cellulose and other water-soluble high weight compounds use mixture, become transparent, higher viscosity. The gelation temperature of low viscosity products is higher than high viscosity of products. Its solution is stable at room temperature. In recent years, It has been widely used in petroleum chemical industry, papermaking, leather, textile printing and dyeing, pharmaceutical, food, cosmetics and other industries, and as the dispersing agent, thickening agent, adhesive, excipient, capsule, oil resistant coating and packing etc.
Hydroxypropyl Methyl Cellulose,HPMC Cellulose Ether
Chemical Properties 
Appearance: white or whitish powder.
Particle size: 80 pass rate >98.5%
Temperature: 280-300 degrees Celsius.
Apparent density: 0.25 - 0.79g /cc (usually at 0.5 g/cc); specific gravity: 1.26-1.31g / cc.
Color changing temperature :190-200 degrees Celsius.
Surface tension: 2% aqueous solution: 42-56 Dyn/cm.
Water Retention: The water retention will be enhanced, which is helpful with such problems as cement or gypsum construction material drying too fast and poor hardening or cracking due to insufficient hydration.
Operationality: It can enhance the plasticity of mortar and improve the coating efficiency in construction projects.
Adhesivity: It can make mortar attach to base material better since the plasticity of mortar is enhanced.
Slip Resistance: It can prevent slipping problem between mortar and the base material in construction project as a result of its thickening effect.
