Hydroxypropyl Methyl Cellulose (HPMC) Industrial Grade Thickener for Construction Mortar

Hydroxypropyl methylcellulose HPMC is easily soluble in cold water, and it will be difficult to dissolve in hot water. But its gelation temperature in hot water is significantly higher than that of methyl cellulose. The dissolution in cold water is also greatly improved compared to methyl cellulose.

Hydroxypropyl methylcellulose (HPMC) Industrial Grade Thickener for Construction Mortar

Hydroxypropyl methylcellulose HPMC

HPMC Product Properties: HPMC is a white or slightly yellow powder, and is odorless, tasteless and non-toxic.


Water solubility and thickening ability: HPMC can be dissolved in cold water to form a transparent viscous solution.


Dissolution in organic solvents: Because HPMC contains a certain amount of hydrophobic methoxy group, this product can be dissolved in some organic solvents, and it can also be dissolved in water and organic solvents.


Salt resistance: Since HPMC is a non-ionic and non-polyelectrolyte, it is relatively stable in aqueous solutions of metal salts or organic electrolytes.


Surface activity: The aqueous solution of HPMC as surface activity, making it emulsify, protect colloids and relative stability.


Thermal gelation: When heated to a certain temperature, the aqueous solution of HPMC can become opaque, generate precipitation, and make the solution lose viscosity. But it changed to its original solution state after gradually cooling. The temperature at which condensation and precipitation occur depends on the type of product, the concentration of the solution and the heating rate.


Low ash content: Because HPMC is non-ionic, it can be effectively refined by washing with hot water during the preparation process, so its ash content is very low.

 PH stability: The viscosity of the aqueous solution of HPMC is relatively stable within the range of PH3.0-11.0.


Water retention effect: Because HPMC is hydrophilic and its aqueous solution is high viscosity. It is added to mortar, gypsum, paint, etc., to maintain high water retention in the product.


Shape retention: Compared with other water-soluble polymers, the aqueous solution of HPMC has special viscoelastic properties. Its addition has the ability to improve the shape of extruded ceramic products.


Lubricity: Adding HPMC can reduce the coefficient of friction and improve the lubricity of extruded ceramic products and cement products.


Film formation: HPMC can produce strong, flexible, transparent flakes with good oil and ester resistance
