What is redispersible polymer powder

Redispersible polymer powder is a powder dispersion produced and processed from a modified polymer emulsion. It has good redispersibility and can be re-emulsified into a stable polymer emulsion after adding water. Its chemical properties Exactly the same as the initial emulsion, thus making it possible to produce high-quality dry-mixed mortars with:


  • Stronger adhesion and mechanical properties

  • Excellent elasticity

  • outstanding water resistance

  • Excellent alkali resistance and abrasion resistance

  • Increase open time, improve workability

The modification of the mortar by the redispersible polymer powder is realized by the polymer forming a film with high adhesion between the cement slurry and the aggregate, and blocking the voids in the mortar. Cement hydration and polymer film formation proceed simultaneously, and finally an interpenetrating network structure in which cement slurry and polymer film are interwoven is formed. The polymer with reactive groups will chemically react with the silicate on the surface of solid calcium hydroxide to improve the bond between the cement hydration product and the aggregate, thereby improving the performance of the mortar.

Redispersible polymer powder uses

Redispersible latex powder is widely used in external wall insulation system, tile adhesive, caulking agent, self-leveling mortar, repair mortar, putty, decorative mortar, diatom mud, waterproof slurry, wear-resistant floor and other fields.

(1) Improve the bonding strength: the latex powder at the interface forms a film

(2) Improve cohesion: film formation on the capillary wall and film formation at micro-cracks

(3) Improve the airtightness and water resistance of mortar: film formation on capillary walls, film formation at micro cracks, latex powder film is waterproof

(4) Improve the flexibility and deformation ability of the mortar: latex powder is a low elastic modulus to change the rigidity of the cement base, and the latex powder bridges the mortar to supplement micro-cracks

(5) Improve mortar workability: ball effect of latex powder particles, air-entraining effect of latex powder emulsion.

Redispersible polymer powder for tile adhesive

RDP VAE plays a bonding role in tile adhesives, has strong adhesion and bonding strength to walls, and is suitable for various high and low grade tiles.

The amount of latex powder per ton of tile adhesive should not be less than 1.5%. It is not recommended to add polyvinyl alcohol. Polyvinyl alcohol is not water-resistant, which is not conducive to the long-term use of ceramic tiles, especially when the exterior walls of buildings and indoor toilets are exposed to water. relatively large place.


Redispersible polymer powder factory

Redispersible polymer powder factory refers to RDP suppliers with production capacity, and the purchase of redispersible polymer powder (VAE RDP) is generally purchased through manufacturers. In this way, the quality of the product can be guaranteed, and at the same time, the price is more competitive than that of the middleman.


Hebei YIDA is the top redispersible polymer powder factory in China. It has 17 years of professional experience, 4 production lines, and an annual output of 26,000 tons. It also has advanced experimental equipment and can provide free technical support and sample services.
