Technical Specifications of High Viscosity 200000 HPMC Powder

Hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether derived from natural cellulose through chemical modification. The "200000" in its designation refers to its nominal viscosity, typically measured in mPa·s (or cP) for a 2% aqueous solution at 20°C using a Brookfield viscometer. This high viscosity indicates a polymer chain structure that imparts exceptional thickening and water retention capabilities crucial for industrial applications.

The performance of High viscosity 200000 HPMC powder industrial grade hydroxypropyl methyl cellulose ether is defined by a precise balance of physical and chemical parameters, ensuring consistent and reliable results across various formulations. Key technical specifications include:

These specifications highlight the controlled manufacturing process and the resulting superior quality, which directly translates to enhanced performance in various applications. The high degree of polymerization and targeted substitution of methoxyl and hydroxypropoxyl groups are critical for achieving the desired viscosity and functional properties.

The Manufacturing Process: From Raw Materials to Advanced HPMC

The production of High viscosity 200000 HPMC powder industrial grade hydroxypropyl methyl cellulose ether is a sophisticated chemical process involving precise control over reaction conditions, purification, and particle engineering. The core raw material is high-purity refined cotton linter, a renewable resource known for its high cellulose content. The manufacturing process generally proceeds through several key stages:

1. Alkalization:

Refined cellulose is steeped in an aqueous solution of sodium hydroxide (NaOH) to activate the cellulose. This process, known as alkalization, swells the cellulose fibers, making the hydroxyl groups on the anhydroglucose units more accessible for subsequent etherification reactions.

2. Etherification:

The alkali cellulose is then reacted with methyl chloride (CH₃Cl) and propylene oxide (C₃H₆O) in a highly controlled, pressurized reactor. These reactants introduce methoxyl and hydroxypropoxyl groups, respectively, onto the cellulose backbone. The degree of substitution (DS) and molar substitution (MS) of these groups are critical in determining the final properties, including viscosity, solubility, and gelation temperature. Precise control during this stage is vital for achieving the target 200,000 mPa·s viscosity.

3. Neutralization:

After the etherification reaction, residual alkali is neutralized using acids such as acetic acid or hydrochloric acid. This step ensures the pH of the product is within the desired range for stability and application compatibility.

4. Washing and Purification:

The crude HPMC is subjected to extensive hot water washing to remove impurities, unreacted reagents, and soluble by-products (e.g., sodium chloride). This purification step is crucial for achieving the high purity required for industrial-grade HPMC, ensuring minimal impact on end-product performance and compliance with various international standards like ISO and ANSI.

5. Drying:

The purified HPMC cake is then dried using advanced drying technologies (e.g., flash drying or fluidized bed drying) to reduce its moisture content to specified levels. Controlled drying prevents thermal degradation and maintains product integrity.

6. Grinding and Sieving:

Finally, the dried HPMC is ground into a fine powder and sieved to achieve a consistent particle size distribution. This is essential for ensuring rapid dissolution, uniform dispersion, and optimal performance in various formulations. Quality control checkpoints are integrated throughout the entire process, including raw material inspection, in-process testing of reaction parameters, and final product analysis to ensure every batch meets the stringent industrial-grade specifications. The typical service life of such HPMC powder, when stored correctly, is around 2 years, retaining its functional properties effectively.

Key Application Scenarios and Target Industries

The high viscosity and excellent water retention of High viscosity 200000 HPMC powder industrial grade hydroxypropyl methyl cellulose ether make it indispensable across a spectrum of industrial applications. Its unique properties are leveraged to enhance workability, adhesion, sag resistance, and overall durability in various formulations.

Construction Industry:

• Tile Adhesives (e.g., C2TE grade): HPMC provides extended open time, improved adhesion to various substrates (e.g., concrete, gypsum board), and enhanced anti-sag properties for heavy tiles. Its water retention capabilities prevent premature drying of the adhesive, ensuring optimal cement hydration and bond strength.
