Unleashing the Potential of HPMC in Gypsum Plaster and Beyond
October 22nd 2024
PROPERTIES OF HPMC for Drymix Mortar:
* 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. Dry mortar additives are nonionic surface active agents. 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%.
Construction grade Hydroxyporpyl Methyl Cellulose(HPMC)
Construction grade HPMC CAS9004-65-3 is widely used in drymix mortar products, including tile adhesives, plastering mortar, grouts, and self-leveling compounds. Could be soluble in water and form the transparent solution. As the important dry mortar additives, Hydroxyproypl methyl Cellulose could increase the water retention, increase the workability and increase open time etc. As a professional manufacturer of fine chemical cellulose ether, we offer a range of drymix mortar additives include HPMC and VAE/RDP powder.
