  • Applications of HPMC Sheets


  • Density, in a general sense, is defined as mass per unit volume. For HPMC, its density can vary depending on several factors, including the degree of substitution, molecular weight, and the specific formulation used. Generally, HPMC possesses a bulk density ranging from 0.3 to 0.6 g/cm³, with variations influenced by its viscosity grades and water content. Understanding HPMC density is crucial for formulators, as it affects the flow properties, dissolution rates, and the overall efficacy of the final product.


  • Overall, HPMC for putty powder is an essential ingredient that enhances the performance, quality, and durability of putty. Its versatile properties make it a key component in the formulation of high-quality putty products. Whether used for interior or exterior applications, HPMC for putty powder helps in achieving a professional finish that is strong, durable, and long-lasting.
  • Additionally, HPMC is often found in gluten-free and low-fat products to provide a desirable texture that might otherwise be lost. Its stabilizing properties help maintain emulsions, ensuring that ingredients remain uniformly dispersed throughout the product, which is vital for quality control in food manufacturing.


  • One of the most prominent uses of HPMC is in the pharmaceutical industry. It serves as a critical excipient in the formulation of controlled-release drug delivery systems. HPMC can form a gel-like substance upon contact with water, which allows for the slow and sustained release of active pharmaceutical ingredients (APIs). This property helps improve the bioavailability of drugs and provides therapeutic effects over extended periods. Additionally, HPMC is used as a binder in tablet formulations, ensuring that the tablets maintain their integrity and provide consistent dosages.


  • The integration of HPMC in detergent formulations presents numerous advantages, from enhancing viscosity and stability to serving as a binder and improving moisture retention.
