Hydroxypropyl Methyl Cellulose - Hebei Tangzhi Technology | Thickener, Water Retention

What is Hydroxypropyl Methyl Cellulose (HPMC)?

Hydroxypropyl Methyl Cellulose (HPMC), also known as CAS 9004-65-3, is a high-performance multifunctional thickener and stabilizer derived from natural cellulose. This non-ionic cellulose ether is widely used in construction, medicine, food, and daily chemical industries due to its exceptional properties. HPMC is available in two types: hot-dissolving and instant-dissolving, each tailored for specific applications.

Key Features and Advantages of HPMC

• Excellent Thickening Effect: Enhances viscosity in surfactants and other formulations, ensuring smooth application and stability.
• Superior Water Retention: Prevents rapid drying and cracking in mortars, coatings, and adhesives, extending working time.
• Strong Bonding Properties: Improves adhesion in construction materials, reducing slippage and enhancing durability.
• Thermal Stability: Maintains performance under varying temperature conditions, ideal for hot-melt applications.
• Non-Toxic and Safe: Odorless, tasteless, and non-irritating, making it suitable for pharmaceutical and food-grade use.

Applications of HPMC in Various Industries

1. Construction Industry

HPMC for Gypsum improves the workability of plaster, enhances anti-vertical flow properties, and ensures uniform surface coating. HPMC also prolongs the working time of mortar, resulting in high mechanical strength during solidification.

2. Adhesives and Coatings

HPMC for Adhesive ensures easy mixing of dry ingredients, reduces lumps, and improves adhesion. Its water retention properties enhance the efficiency of brick pasting and reduce construction costs.

3. Mortar and Cement Applications

HPMC for Mortar provides viscosity, prevents sedimentation, and improves fluidity for efficient paving. It also controls water retention, minimizing cracking and ensuring durable results.

4. Wall Putty and Insulation Mortar

HPMC for Wall Putty enhances water retention, reduces shrinkage, and improves surface quality. For HPMC for Exterior Wall Insulation Mortar, it strengthens adhesion to walls and eliminates micro-cracks, creating a smooth finish.

Production Process of HPMC

1. Raw Material Preparation: High-quality methyl cellulose and propylene oxide are selected, ensuring compliance with production standards.
2. Reaction Process: The raw materials are mixed under controlled temperature and pressure, with catalysts facilitating the etherification reaction.
3. Refining Process: Crude HPMC is centrifuged, washed, and dried to remove impurities and unreacted chemicals.
4. Packaging and Storage: The final product is packed in multi-layer paper bags (25 kg net weight) and stored in cool, dry conditions to maintain quality.
