RDP

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.

Redispersible polymer powder (RDP) demonstrates exceptional application value across multiple fields, significantly enhancing the performance and durability of building material systems.

Below are the core characteristics of our factory's redispersible polymer powder:

  • Excellent bonding properties, enhanced material strength

RDP significantly enhances the bonding strength of materials such as mortar, putty powder, and tile adhesive, effectively preventing hollow spots and detachment while improving construction quality and durability.

  • Improves Flexibility and Enhances Crack Resistance

Possesses excellent flexibility and ductility, effectively alleviating stress concentration issues and improving the material's crack resistance. Suitable for insulation systems and exterior wall coatings.

  • Excellent Dispersibility, Easy Application

Rapidly disperses in water to form a stable emulsion, ensuring uniform distribution within formulations while minimizing lumping and separation.

  • Enhanced Water Retention, Improved Workability

Forms a dense polymer film in mortar to boost water retention, extend workability time, and improve application smoothness.

  • Exceptional weather resistance for diverse environments

Forms a continuous, flexible, and durable polymer film with outstanding alkali resistance, freeze-thaw resistance, and UV stability, suitable for both indoor and outdoor applications.

  • Enhanced abrasion and impact resistance

The polymer film improves material durability against wear and impact, ensuring long-term stability. Widely used in flooring and high-strength mortar systems.

  • Excellent compatibility and formulation adaptability

It bonds well with inorganic cementitious materials like cement, gypsum, and lime, and can coexist with various additives without compromising system stability.

  • Environmentally friendly and safe, meeting green standards

RDP is an eco-friendly polymer powder, non-toxic and harmless, complying with green building and sustainable development requirements. It is suitable for projects with stringent environmental performance demands.
