HPMC

HPMC(Hydroxypropyl methyl lose)Hydroxypropyl Methyl loseare types of non-ionic lose ether, which are a powder of white to off white color, that function as a thickener, binder, film-former, surfactant, protective colloid, lubricant, emulsifier and suspension and water retention aid. In addition, there types of lose ethers exhibit properties of thermal gelation, metabolic inertness, enzyme resistance, low odor and taste, and stability. Due to the myriad of properties, HPMC is often used to substitute many other additives with lower concentration, making HPMC an incredibly efficient and effective additive in area of adhesives, construction, foods, household products, rmaceuticals and etc.

SICAL AND CHEMICAL PROPERTIES:* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.* Charring temperature: 280-300ºC.* Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )* Real specific gravity: 1.26-1.31.* Browning temperature: 190-200ºC.* Surface tension: (2% water solution) .* Properties: Dissolved in water and some organic solvent such as ethanol. propyl alcohol. ethylene chloride, the water solution is of surface activity. It is a nonionic surface active agent. Gelation temperature is different for different grades. For example, among 60RT Hydroxypropyl Methyllose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%
