MHPC Hydroxypropyl Methyl Cellulose
VAMCELL Hydroxy propyl Methyl Cellulose
VAMCELL is our registered trademark of Cellulose ethers
Introduction:
VAMCELL MHPC is made by propylene oxide, methyl chloride with alkali-cellulose after a chemical process called Etherification under rigidly controlled conditions. The resultant nonionic polymer is purified, dried and ground to a fine white powder, this water-insoluble cellulose is turned into water-soluble nonionic polymer, HPMC is a good film-former and varies somewhat in physical and chemical properties. HPMC is quite hydrophilic and readily soluble in cold water.
