HPMC HEMC is nonionic cellulose ether, It was produced from highly pure refined cotton or Pulp wood. HPMC 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→HPMC HEMC powder.
Features:
Excellent workability High water retention
Improve substrate adhesion Rheology
Surface treatment Long open time
High gelation temperature Shape retention
Anti-slip Lower ash
Thickening
