Technical Parameters
HPMC
Hydroxypropyl Methylcellulose (HPMC) is a non-ionic cellulose ether, derived from natural cellulose through chemical modification. HPMC boasts excellent properties such as thickening, water retention, adhesion, film-forming, and emulsifying stability, and is widely applied in industries including building materials (e.g., dry-mix mortar, tile adhesive), coatings, pharmaceuticals, food, daily chemicals, and oil extraction.
Excellent water retention
Good thickening and suspending properties
Film-forming and adhesive properties
