HPMC(Hydroxypropyl Methyl Cellulose)

Hydroxypropyl methylcellulose (HPMC), a non-ionic cellulose ether, is derived from natural cellulose through a rigorous series of chemical processes. This white powder is characterized by its odorless and tasteless nature, rendering it non-toxic and safe for various applications. One of its notable features is its ability to dissolve in cold water, resulting in a transparent viscous solution. HPMC possesses a broad range of functional properties, including thickening, adhesion, dispersion, emulsification, and film-forming capabilities. Additionally, it excels in moisture retention, gelation, and surface activity, making it a versatile compound across numerous industries, such as pharmaceuticals, food production, construction, and cosmetics.

Application Scenarios

Tile Adhesives

Extends open time and adjustability; reduces vertical tile slippage; enhances bond strength; improves workability during plastering and tiling.

Putty

Provides high water retention to prevent cracking and powdering; ensures smooth application and easy sanding; extends working time; improves the density and adhesion of the putty layer.

Self-Leveling Mortar

Acts as a thickener to prevent aggregate sedimentation; controls flowability within an optimal range; retains water to promote uniform hydration; minimizes shrinkage and cracking, resulting in superior floor flatness.

Gypsum Products

Retards the setting rate of gypsum; retains water to prevent premature drying and surface dusting; improves application workability; enhances the strength and crack resistance of gypsum-based products.

Daily Chemicals

HPMC (Hydroxypropyl Methylcellulose) is a water-soluble polymeric thickener, film-former, emulsion stabilizer, and moisture-retention agent, widely used in hair care, skincare, and daily cleaning products.

Coatings

Thickening and Anti-sagging; Water Retention and Delayed Drying; Improved Workability
