Redispersible polymer Powder Properties


1.Improve the bending and flexural strength of mortar. HWZK brand redispersible polymer powder has good flexibility.A film is formed between the cement mortar particles and on the surface to form a flexible connection.The weight makes the brittle cement mortar elastic.The tensile resistance of mortar with redispersible polymer powder is several times higher than that of ordinary mortar.

2.Improve the bonding strength and cohesion of mortar. The film of redispersible polymer powder, as an organic binder can form high tensile strength and bonding strength on different substrates.It plays an important role in the adhesion between mortar and organic material (EPS, extruded foam board) and smooth surface substrate.As a reinforcing material, the polymer powder formed by film is distributed in the whole mortar system to increase the cohesion of the mortar.

3.Improve the impact resistance, durability and wear resistance of mortar. The rubber powder particles fill the pore cavity of the mortar, the compactness of the mortar is increased and the wear resistance is improved.Under the action of external forces, it will be relaxed without being destroyed.The polymer film can exist permanently in the mortar system. 4.Improve the weather resistance and freeze-thaw resistance of mortar and prevent mortar from cracking. Redispersible polymer powder belongs to thermoplastic resin which has good flexibility can make the mortar cope with the change of external cold and hot environment and effectively prevent the mortar from cracking due to the change of temperature difference.

5.Improve the construction and workability of mortar. There is a lubrication effect between the polymer rubber powder particles, so that the components of the mortar can flow independently, at the same time, the rubber powder has an inducing effect on the air which gives the compressibility of the mortar and improves the construction and workability of the mortar.
