Redispersible Polymer Powder RDP Powder VAE Powder

Description of Redispersible Polymer Powder RDP Powder VAE Powder:

Particle morphology and size distribution

The particle shape of re-dispersible rubber powder RDP is usually spherical, the particle size distribution is relatively narrow, and the particle size is generally between 10 and 40 microns. These particles have a high specific surface area, making them well dispersed in water.

Chemical composition

The main component of re-dispersible rubber powder RDP is a polymer, usually a synthetic resin or a natural resin. These polymers have good bonding and film-forming properties and can form flexible films after dispersing in water, providing good bonding and protection properties.

Physical property

The physical properties of re-dispersible rubber powder RDP include density, hardness, elastic modulus, etc. These properties depend on its chemical composition and preparation process. In general, the density of the re-dispersible rubber powder is between 1.0-1.3 g/cm ³, the hardness is low, and the elasticity and flexibility are good.

Stability

Redispersible rubber powder RDP has good stability and can maintain its performance in water for a long time. In preparation and use, there is generally no precipitation or stratification. In addition, the re-dispersible rubber powder also has a low hygroscopic property, which can maintain its performance in wet environments.

Solubility

Redispersible rubber powder RDP has good water solubility and can disperse quickly in water and form a uniform solution. This solution has good rheology and stability and can play an essential role in coatings, adhesives, etc.

Bond property

Redispersible adhesive powder RDP has excellent bonding properties. It can form a flexible film with good bonding and protection properties when dispersed in water. This adhesive powder has a wide range of applications in construction, paint, paper coating and other fields, which can improve the material's strength, toughness, weather resistance and other properties.

Environmental protection property

Redispersible rubber powder RDP has low toxicity, and the raw materials and solvents used in the production process are usually environmentally friendly. In addition, the re-dispersible rubber powder can be easily washed off with water after use without causing harm to the human body and the environment. Therefore, re-dispersible rubber powder is a relatively environmentally friendly building material.

Applications of Redispersible Polymer Powder RDP Powder VAE Powder: 

Architectural field

In construction, dispersible adhesive powder RDP is widely used to prepare architectural coatings and adhesives. Because its excellent bonding and film-forming properties can provide good bonding and protection properties, it is widely used in cement mortar, gypsum board, thermal insulation materials, and other building materials' bonding and plastering. In addition, dispersible adhesive powder RDP is also used to prepare resilient flooring, tile adhesives, waterproof coatings and other building materials.

Paint field

Redispersible adhesive powder RDP is also widely used in the field of coatings. Because of its good stability, solubility and bonding properties, it is used to prepare various water-based coatings, latex paints, wallpaper coatings, etc. In the process of use, the dispersible adhesive powder RDP can provide good film formation and hiding power while also improving the coating's weatherability, water resistance and scrubbing resistance.

Paper coating area

In the field of paper coating, dispersible adhesive powder RDP is used to improve paper's strength, toughness and water resistance. Because of its excellent bonding performance and film formation, it can form a protective film on the paper's surface, improving the paper's water and friction resistance. At the same time, the dispersible adhesive powder RDP is also used to prepare various coated paper, decorative paper and so on.



Production Method of Redispersible Polymer Powder RDP Powder VAE Powder: 

Raw material preparation

The production of re-dispersible rubber powder RDP requires the preparation of various raw materials, including synthetic resins, fillers, pigments, auxiliaries, etc. These ingredients must be weighed and mixed proportionately to the formula to ensure accuracy and consistency.

Melt extrusion

The weighed raw material is added to the extruder and melted and extruded at high temperatures. This step mainly melts and mixes the raw materials to form a uniform material.

Grinding dispersion

After melting and mixing, the material is cooled and ground to obtain the dispersible adhesive powder RDP in powder form. In the grinding process, it is necessary to control the grinding time and grinding strength to ensure that the re-dispersible rubber powder's particle size and particle size distribution meet the requirements.

Dry and sift

The ground dispersible rubber powder is dried and screened to remove moisture and impurities, and the dry and pure dispersible rubber powder is obtained. During the drying and screening process, attention should be paid to controlling temperature and humidity to avoid moisture or caking of the re-dispersible rubber powder.

Packaging and storage

The dry, pure, dispersible adhesive powder is packed and stored. Packaging materials generally use polyethylene or polypropylene film with good sealing performance to prevent moisture or contamination of re-dispersible rubber powder. During the storage process, attention should be paid to maintaining ventilation, dryness, coolness, and other conditions to ensure the quality and stability of the re-dispersible rubber powder.

Quality control

The production process needs strict quality control, including raw material quality control, production process control, product quality inspection and so on. Quality control is the key to ensuring the quality and stability of re-dispersible rubber powder RDP.



Packaging and storage Redispersible powder:

Redispersible polyester powder should not be stored in direct sunlight. Six months is the recommended time for use.

When you use  in the summer, please make sure to use  edispersible Powder as soon possible.

Edispersible powder can increase the chances of agglomeration when stored in a hot, humid place.

Please make sure to use edispersible Powder as soon as possible after opening the bag.
