HEMC is nonionic cellulose ether, It was produced from highly pure refined cotton or Pulp wood. HEMC was produced by Refined cotton→ Reaction kettle→vacuumize→alkalify→etherification( methyl chloride or propylene oxide or ethylene oxide )→washing and Adjust PH to neutral---Dry and pulverize→HEMC powder.
