  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%.
  
  Packing and Storage
  Standard Packing: In 25kg bags out HDPE bags with inner plastic bags.
  Store it in a cool, dry place below 30degree and protected against humidity and pressing, since the goods is thermoplastic, storage time should not exceed six months.
