Redispersible polymer powder RDP powder supplied by factory source
Redispersible polymer powder RDP is an organic binder powder made by spray drying a special emulsion (high molecular weight polymer). This powder can quickly redisperse into an emulsion upon contact with water, retaining the same properties as the initial emulsion. In other words, it forms a film after water evaporation.
Redispersible polymer powder RDP can improve:
1. mortar performance, 2. increase mortar strength,
3. enhance the bond strength between mortar and various substrates, 4. improve the mortar's flexibility and deformability,
5. compressive strength, flexural strength, abrasion resistance, toughness, adhesion, water retention, and workability.
Techinical Guide
| Property | Flexible RDP | Semi-Flexible RDP |
|---|---|---|
| Glass Transition Temp (Tg) | Typically below 0°C (e.g., −15°C to 5°C). | Typically around 0°C (e.g., −5°C to 10°C). |
| Elongation & Flexibility | High elongation at break; forms a highly elastic polymer film. | Moderate elasticity; balances flexibility with rigid support. |
| Tensile & Cohesive Strength | Moderate tensile strength; prioritizes deformation absorption. | High tensile strength and superior initial adhesion. |
| Primary Target Problem | Thermal expansion, structural vibration, and severe cracking. | Standard deformation resistance combined with high load-bearing capacity. |
Features
1. Flexible RDP imparts excellent tensile flexibility to prevent the surface from cracking due to thermal stress.
2. Redispersible polymer powder RDP is used to bond insulation boards to the concrete wall. It delivers robust bond strength while absorbing stress caused by structural deformations.
3. Flexible redispersible polymer powder RDP absorbs the shear stress generated by the differential thermal expansion between the tiles and the substrate, completely preventing tile warping, hollow spots, or detachment.
