  • One of the premier advantages of incorporating HPMC into gypsum plaster is its ability to improve workability. HPMC acts as a thickening agent, enhancing the viscosity of the plaster mix. This results in a paste that is easier to apply and spread while minimizing the risk of sagging during application. Professionals can achieve a more uniform and even layer, which is essential for both aesthetic and structural purposes. The improved workability allows for longer open time, giving applicators more flexibility to work with the product without rushing.


  • Advantages of Using Redispersible Powders


  • The use of redispersible powder for construction operation is simple and fast. The construction personnel only need to add it to the building materials before use, stir it evenly and then add water, without complex processes and equipment. In addition, due to the absence of harmful substances such as organic solvents, RDP does not produce harmful gases and dust pollution dur process, ensuring the safety and health of construction personnel.

  • - The K series is characterized by a high viscosity and is primarily used in pharmaceutical applications. The 'K' indicates the viscosity level, with higher numbers corresponding to greater viscosity. For instance, HPMC K4M has a low viscosity, while HPMC K100M has a high viscosity. These variations allow formulators to select the appropriate HPMC type for their specific needs.
  • HPMC is derived from natural cellulose through a series of chemical modifications. This process introduces hydroxypropyl and methyl groups into the cellulose polymer chain, altering its physical and chemical properties. The result is a product that not only enhances the viscosity of solutions but also improves film-forming, emulsifying, and stabilizing capabilities. The extent of hydroxypropyl and methyl substitutions can be tuned to obtain specific properties, making HPMC a highly customizable material.


  • 3. Specific Applications HPMC grades can be further classified based on their intended use. For instance, pharmaceutical grades are specifically formulated for drug delivery systems, while food-grade HPMC is utilized as a thickener and stabilizer in food products.
