Hydroxypropyl Methyl Cellulose (HPMC) is a highly adaptable polymer, finding its way into an astonishing array of products. For formulators, selecting the correct HPMC grade is not just about finding a thickener; it's about optimizing performance, ensuring stability, and achieving the desired end-product characteristics. As a premier HPMC manufacturer and supplier in China, we specialize in guiding our clients to the perfect HPMC for their unique needs.

The selection process for HPMC (CAS 9004-65-3) hinges on understanding the interplay between its various grades and the specific requirements of your application. The primary differentiating factors typically include viscosity, degree of substitution (methoxy and hydroxypropyl content), and particle size.

Matching HPMC to Your Application:

  • For Construction: When formulating tile adhesives, renders, or mortars, the key properties are water retention and workability. Industrial grades with higher viscosities, such as those offering 10,000 cP or more, are often preferred for their superior water-binding and thickening effects. These grades prevent premature drying and improve the consistency of the mix. If you're looking to buy HPMC for construction, ask about grades like our TNJ-30000 or higher.
  • For Pharmaceuticals: In pharmaceutical applications, HPMC is crucial for controlled release, granulation, and film coating. Pharmaceutical grades are essential, and the chosen viscosity grade dictates the release rate of the active ingredient. Lower viscosity grades (e.g., 4-60 mPa.s) are common for tablet coatings, while higher viscosity grades (e.g., 4,000-100,000 mPa.s) are used for sustained-release matrices. We offer specific Pharma grades tailored for these precise needs.
  • For Food and Cosmetics: Food and cosmetic applications often require HPMC with excellent emulsifying, thickening, and suspending properties. Food grades must meet stringent regulatory standards. Cosmetic grades enhance the texture and stability of products like lotions and shampoos. Grades with moderate viscosities often strike a good balance for these applications.

Key Selection Parameters:

  • Viscosity: This is often the most critical parameter. A 2% aqueous solution viscosity ranging from 4 mPa.s to over 100,000 mPa.s offers a broad spectrum of functional possibilities.
  • Hydroxypropyl and Methoxy Content: These substitution levels influence gelation temperature, solubility, and surface activity, impacting performance in specific formulations.
  • Particle Size: While less common as a primary selection criterion, it can affect dissolution rate.
