HPMC For Self-leveling Mortar
Hydroxypropyl Methyl Cellulose HPMC
Made from natural cotton fiber by chemical processing, Hydroxypropyl Methyl Cellulose (HPMC) CAS9004-65-3 is non-ionic cellulose and can be dissolved in cold water to form a transparent viscous solution. It’s tasteless, odorless and non-toxic white powder, with the characteristics of binding, thickening, dispersing, film coating, emulsifying, absorbing, suspending, gelling, water retention and colloid protection.

PHYSICAL AND CHEMICAL PROPERTIES:
* Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.
* Charring temperature: 280-300℃.
* Bulk density: 0.25-0.70 g/cm3 (Usually around 0.5 g/cm3 )
* Real specific gravity: 1.26-1.31.
* Browning temperature: 190-200℃.
* Surface tension: (2% water solution) 42-56dyn.cm.
* 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 Methylcellulose, 60 is gelation temperature, Namely, 2% water solution will form gelation at 60%.
