Redispersible Polymer Powder RDP Made From Ethylene-Vinyl Acetate Copolymer Emulsion
Redispersible Polymer Powder is an innovative building material additive derived from advanced spray drying technology that can significantly improve the overall performance of mortar and concrete.
Description
Introduce of Redispersible Polymer Powder RDP Made From Ethylene-Vinyl Acetate Copolymer Emulsion
Redispersible Polymer Powder (RDP), also known as redispersible latex powder, is a powdered polymer formed by spray drying of polymer emulsion. This powder can be dispersed again to form a stable emulsion after contacting water. It is widely used in construction chemicals such as dry-mix mortars, tile adhesives, plastering mortars, and self-leveling floor materials to enhance the adhesion, waterproofness, and Flexibility and durability.
Features of Redispersible Polymer Powder RDP Made From Ethylene-Vinyl Acetate Copolymer Emulsion
Enhanced bonding force: Significantly improve the bonding strength between mortar and other base materials, reducing hollowing and falling off.
Improve flexibility: Give cement-based materials better stretchability and crack resistance, effectively resisting cracking caused by temperature changes and vibration.
Improve durability: Enhance the material’s impermeability, freeze-thaw resistance and chemical corrosion resistance to extend its service life.
Easy construction: Improve the plasticity and opening time of mortar to facilitate construction operations and adjustments.
Environmental protection: no solvent evaporation, meets environmental protection requirements, and is suitable for green building construction.
Good compatibility: Compatible with a variety of cement-based materials and can be widely used in different types of building materials.

Parameter of Redispersible Polymer Powder RDP Made From Ethylene-Vinyl Acetate Copolymer Emulsion
The Redispersible Polymer powder RDP made from ethylene-vinyl acetate copolymer emulsion parameter can be calculated using various parameters such as temperature, flow rate, time of exposure, and pressure.
First, we need to determine the specific formula for the polymer used in the RDP mixture:
EVA-copolymers are a class of polymers that can form solid polymer powders with a high melting point (130°C or above), low viscosidade, high mechanical strength, and good compatibility with a wide range of liquids.
Next, we can calculate the molar mass of the polymer:
EVA-copolymers have a general formula for molar mass: [Mm] = [M ] / [C]
where [M] is the molecular weight of the polymer, and [M ] is the coefficient of adhesiveness of the polymer to the target surface material.
Finally, we can use the given molar mass to calculate the concentration of the polymer mixture:
Concentration of polymer mixture = [Mm] / [C]
This will give us the concentration of the polymer in grams per liter (g/L). We can also adjust this value based on the desired content of the RDP and the size of the individual parts of the powder. For example, if we want a higher concentration of the polymer, we can increase the concentration by multiplying the molar mass by the concentration. If we want a lower concentration, we can decrease the molar mass.
Once we have the concentration of the polymer, we can calculate the volume of the RDP mixture at different operating conditions. For example, we can vary the flow rate, time of exposure, and pressure to find the optimal balance between moisture retention, film formation, and performance characteristics.
