Top quality redispersible polymer powder supplied by factory
Semi-flexible redispersible polymer powder strikes an optimal balance between rigid bond strength and flexibility/crack resistance. When mixed with water and cement/gypsum, redispersible polymer powder forms a continuous polymer film within the mineral matrix, transforming brittle mortars into tough, highly adhesive, and flexible building materials.
Core Performance Benefits
● Balanced Mechanical Properties: redispersible polymer powder combines structural compressive strength with flexible crack-bridging capability.
● Superior Adhesion: redispersible polymer powder bonds strongly to diverse organic and inorganic substrates (Concrete, EPS, Glass, Ceramics).
● Enhanced Durability: redispersible polymer powder increases resistance to freeze-thaw cycles, water penetration, and thermal stress.

Techinal Guide
-Similarities (Common Features)
Both flexible and semi-flexible RDPs share core functional properties when modified into cementitious or gypsum-based mortars:
-Key Differences
The primary differences lie in their Glass Transition Temperature ($T_g$), Ethylene content, and the balance between stiffness (compressive strength) and deformability (elasticity).
| Item / Property | Semi-Flexible RDP | Flexible RDP |
|---|---|---|
| Glass Transition Temp (Tg) | Typically around 0°C (e.g., -5°C to 10°C) |
Typically below 0°C (e.g., -15°C to 5°C) |
| Ash Content (灰分) | ≤ 14 ± 2% | ≤ 12 ± 2% (Higher Purity) |
| Film Characteristics | Moderate elasticity with high surface hardness & cohesive support. | Highly elastic, rubber-like film with superior elongation at break. |
| Mechanical Priority | High Tensile & Bonding Strength | Maximum Flexibility & Crack Resistance |
| Target Applications | • Standard Tile Adhesives (C1) • Flexible Tile Grouts • Wall Putty / Skim Coat (Interior/Exterior) • Base-layer Repair Mortars • Standard Self-Leveling Flooring |
• Premium Tile Adhesives (C2/S1/S2) • Large Format Tile/Slab Adhesives • ETICS / EIFS Anti-crack Base Coats • Polymer Waterproof Mortars • Flexible Self-Leveling Flooring |
