  • What is maltodextrin?

    Maltodextrin (MD) is a low-conversion product between starch and starch sugar. White or slightly light yellow amorphous powder in appearance, without visible impurities, with a special smell, not sweet or slightly sweet taste. Its hydrolysis DE value determines the physical properties of maltodextrin. This value indicates the extent of hydrolysis and is a crucial factor in understanding the product's characteristics. In essence, the degree of hydrolysis of maltodextrin determines its DE value. A higher DE value means the product has increased dissolved oxygen, sweetness, permeability, fermentability, browning reaction, and freezing point depression. However, the texture, viscosity, and pigment stability may worsen alongside crystallization resistance. 

    Features of Maltodextrin 

    1. Maltodextrin is a starch hydrolysis product with a DE value of 5-20.

    2. Maltodextrin can be a white powder or concentrated liquid. Good fluidity and no smell.

    3. Maltodextrin has good solubility and moderate viscosity.

    4. Maltodextrin has low hygroscopicity and is not easy to agglomerate.

    5. Maltodextrin is an effective carrier for sweeteners, flavorings, fillers, and other substances. Its carrier effect is highly regarded. It has a good emulsifying and thickening effect.

    6. Maltodextrin has good film-forming performance, which can prevent product deformation and improve product appearance.

    What is maltodextrin used for?

    Adding maltodextrin to building material admixture can delay the hydration heat and slow the solidification. Compared with other retarders, maltodextrin has a better retarding effect and workability for concrete. Maltodextrin can only be used with water-reducing agents and pumping agents because it is a concrete retarder, which can delay the hydration rate of cement so that the concrete can reach the construction site from the station as required.

    Is maltodextrin a natural ingredient?

    Maltodextrin is technically based on nature. Manufacturers derive maltodextrin from starchy foods like potatoes, corn, and wheat. However, it is highly processed.

  • What is redispersible polymer powder powder?

    Redispersible polymer powder products are water-soluble redispersible powders, which are divided into ethylene/vinyl acetate copolymers, vinyl acetate/ethylene tertiary carbonate copolymers, acrylic acid copolymers, etc., and the powders made after spray drying are bonded agent, with polyvinyl alcohol as a protective colloid. This kind of powder can quickly redisperse into an emulsion after contact with water. Due to the high bonding ability and unique properties of redispersible polymer powder, such as water resistance, construction, heat insulation, etc., their application scope is extremely broad.

    Features of Redispersible Polymer Powder

    1. Redispersible polymer powder can improve mortar's bending and flexural strength. The polymer film formed by Redispersible polymer powder has good flexibility. Films are formed in the gaps and surfaces of cement mortar particles to form flexible connections. Thus making the brittle cement mortar elastic. When redispersible polymer powder is added to mortar, it increases the mortar's tensile and flexural resistance several times compared to ordinary mortar.

    2. Redispersible polymer powder can improve mortar's bonding strength and cohesion. When the redispersible polymer powder is made into a film as an organic adhesive, it can create strong tensile and bonding strength on various substrates. This substance plays a crucial part in securing the adhesion of mortar to smooth surface substrates and organic materials like ESP and extruded foam board. The distributed film-forming polymer rubber powder acts as a reinforcing material, enhancing the cohesion of the mortar system.

    3. Redispersible polymer powder can improve the mortar's impact, durability, and wear resistance. By filling the cavity of the mortar, the rubber powder particles increase the density of the mixture and enhance its wear resistance. When subjected to external force, the polymer film can undergo relaxation without sustaining damage, which allows it to remain permanently present in the mortar system.

    4. Adding redispersible polymer powder to the mortar can improve its weather and freeze-thaw resistance, and cracking can be prevented. The redispersible polymer powder is a type of thermoplastic resin that provides good flexibility to the mortar. It allows the mortar to effectively handle changes in external temperature. It effectively prevents the mortar from cracking due to the change in temperature difference.

    5. Redispersible polymer powder can improve the hydrophobicity of mortar and reduce water absorption. Redispersible polymer powder forms a film in the cavity and surface of the mortar. The polymer film will not be dispersed again after water exposure, preventing water intrusion. , improved impermeability. The special one with a hydrophobic effect can disperse latex powder, which has an excellent hydrophobic effect.

    6. Redispersible polymer powder can improve the mortar construction and the lubricating effect between the easy-to-use polymer powder particles so that the mortar components can flow independently. The rubber powder positively impacts the air, which in turn enhances the compressibility of the mortar, resulting in improved construction and easier handling.
