Hydroxypropyl Methylcellulose (HPMC) is a water-soluble non-ionic cellulose offering thickening, water retention, adhesion, and film-forming properties. This product is specifically designed as a binder for honeycomb ceramic carriers used in automotive exhaust purification systems. It dissolves in water, making it suitable for extrusion molding processes, and decomposes into carbon dioxide and water during high-temperature sintering, leaving no residues.
- Tile Adhesives & Putty (Grades: K100M, E15) - High water retention extends open time and enhances workability/bond strength
- Cement Mortars (Grades: E5, E15) - Reduces cracking and improves fluidity/pumpability
- Self-Leveling Compounds (Grade: E5) - Low viscosity ensures superior flow and minimizes segregation
Binder for Honeycomb Ceramic Substrates - Water-soluble support for extrusion; leaves no residue after sintering (decomposes to CO₂+H₂O), ideal for automotive exhaust purification carriers.
- Tablet Coating & Sustained-Release Matrices (Grade: K100M) - High-viscosity grade forms controlled-release barriers and modulates dissolution
- Ophthalmic Solution Thickener (Grade: E5) - Safe/non-irritating, prolongs ocular residence time
- Water-Based Paints (Grade: E15) - Ensures uniform film formation and storage stability
- Shampoo/Toothpaste (Grade: E5) - Low-viscosity grade enhances suspension and texture
Dairy/Sauce Thickening (Food-Grade HPMC) - Improves texture; acts as a gelatin alternative in vegan products
