Physical and chemical properties
*Particle size: 98.5% passes through 100 mesh; 100% passes through 80 mesh.
*Charring temperature: 280-300ºC.
*Bulk density: 0.40-0.70 g/cm3 (Usually around 0.5 g/cm3 )
*Real specific gravity:1.26-1.31.
*Browning temperature: 190-200ºC.
Surface tension:(2% water solution) 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%.
