Hydroxypropyl methyl cellulose is an odorless and tasteless white or slightly yellow powder,usde cellulose as a primary source,which can be otanied from wood or cotton.
Hydroxypropyl methyl cellulose is a water-insoluble polymer,but after a chemical process called Etherification,this water-insoluble cellulose is turned into water-soluble nonionic cellulose ether.
Properties
It has good water solubility,water retention,dispersing ,stable PH value,surface activity,thickening,adhesive,film-smoothability and mold resistance.
Appearance: White powder.
Particle size: 98.0%min through 100mesh.
Charring temperature: 280-300 Deg.C.
Bulk density: 0.25-0.70g/cm3(Usually around 0.5g/cm3)
Real specific gravity: 1.26-1.31
Browning temperature: 190-200 Deg.C.
Surface tension(2% water solution): 42-56 dyn/cm.
