Construction grade HPMC

Construction grade HPMC hydroxypropyl methylcellulose is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. Construction grade HPMC is an odorless, odorless and non-toxic white powder that swells into a clear or slightly turbid colloidal solution in cold water. It has the characteristics of thickening, bonding, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, moisture retention and protective colloid.

Performance of construction grade HPMC:


  • HPMC has salt resistance: Since this product is non-ionic and non-polyelectrolyte, it is relatively stable in aqueous solutions of metal salts or organic electrolytes.
  • HPMC surface properties: The aqueous solution of this product has surface activity, making it emulsify, protect colloids and relative stability.
  • HPMC has pH stability: the viscosity of the aqueous solution of this product is relatively stable within the pH range of 3.0-11.0.
  • HPMC has water retention: Because this product is hydrophilic and its aqueous solution is high viscosity, it is added to mortar, gypsum and paint to maintain high water retention in the product.
  • The lubricity of HPMC: adding this product can reduce the coefficient of friction and improve the lubricity of extruded ceramic products and cement products.
  • The film-forming properties of HPMC: This product can produce strong, flexible, transparent flakes and has good oil and grease resistance.
