Highly flexible Redispersible polymer powder
Redispersible polymer powder is a free-flowing white powder formed by spray-drying EVA emulsion. It readily re-emulsifies and disperses in water to form a stable emulsion. In addition to possessing the superior properties of the original EVA emulsion, its free-flowing powder form offers exceptional convenience and reliability during handling and storage.
Key Features and Performance
High Flexibility RDP is a type of redispersible polymer powder primarily designed to enhance flexibility and deformation resistance. It effectively mitigates cracks in building materials caused by stress, temperature fluctuations, and shrinkage. Suitable for applications such as tile adhesives, self-leveling compounds, and external wall insulation systems, it significantly extends overall service life.
- High Flexibility
Significantly improves material resistance to bending and deformation, mitigating cracking risks from thermal contraction and external forces.
- Strong Impact Resistance
Enhances the impact resistance of mortars and adhesives, withstanding mechanical damage during use.
- Excellent Crack Resistance
Effectively disperses stress, reduces micro-cracks on building surfaces, and boosts overall system stability.
- Excellent Compatibility
Compatible with diverse substrates, delivering reliable performance on tiles, EPS/XPS boards, and thermal insulation mortar systems.
Field of application
High Flexibility RDP is widely used in tile adhesives, exterior wall insulation mortars, self-leveling compounds, and repair mortars. It significantly enhances durability and crack resistance, ensuring buildings maintain stability and aesthetics under long-term environmental exposure.
Tile Adhesives
Enhances flexibility and bonding strength, particularly suitable for large-format tiles and outdoor applications, reducing tile detachment.
Exterior Wall Insulation Mortar
Enhances adhesion between the insulation layer and the substrate, resisting cracking caused by external temperature variations and wind forces.
Self-Leveling Mortar
Enhances material toughness to prevent cracks caused by settlement or compression after construction completion.
Repair Mortar
Enhances the impact resistance and abrasion resistance of the mortar repair layer, extending the service life of the repaired area.
