Hydroxypropyl Methyl Cellulose (hPMC)

MAISI ® Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether polymer based on cellulose. Cellulose is a natural polymer extracted from refined cotton linter and provided as a free flowing powder. Belonging to the cellulose ether group, HPMC is mainly used in building materials, such as tile adhesives and plasters, as rheological modifiers and water retaining agents.MaiSI® HPMC has good retention, thickening property, Stable chemical properties effectively resist alkali attack.
