Redispersible polymer powder suppliers: VAE RDP buyer FAQ

VAE redispersible polymer powder is a spray-dried polymer emulsion that can be re-emulsified into a stable polymer emulsion after water is added. In mortar systems, it can improve bond strength, flexibility, water resistance, flexural strength, plasticity, wear resistance and construction properties.

Applications include interior and exterior building putty, flexible crack mortar, decorative mortar, masonry mortar, plastering mortar, self-leveling mortar, waterproof mortar, repair mortar, interface mortar, external wall insulation mortar, ceramic tile adhesive and tile grout. A putty producer can evaluate the powder in its actual binder and filler system. A flexible crack mortar producer should trial it with the intended substrate and layer design.

For the VAE material, the product specifications include VAE polymer composition, water content of no more than 5.0%, ash content of 12 ± 2%, pH of 5 to 8, 50% water viscosity of 0.5 to 2.0, and a white or off-white powder appearance.

The RDP-T1 data gives granularity of at least 100%, stacking density of 300 to 600 g/L, tensile strength of at least 6.0 MPa and elongation at break of at least 200%. The recorded results for these four items are 110%, 523 g/L, 6.8 MPa and 226%. When requesting a quotation, identify the grade and ask for the specification set that applies to the material being offered.

Yes. The VAE powder is used in interior and exterior building putty and flexible crack mortar. In these systems, it can support adhesion, elasticity, flexural strength, plasticity, wear resistance, water retention and open time.

For wall putty, test the powder with the planned binder, fillers and additives, then assess the application behavior and required adhesion. For flexible crack mortar, use the intended substrate and layer conditions during the trial. Send the formulation type, target performance and raw materials to the supplier when requesting a suitable grade or sample.

Packaging options include 25 kg bags and 500 to 600 kg pallets. OEM appearance support is available. Free sample shipping is offered by FedEx or DHL, and transportation options include sea, land and air freight. Delivery terms include CIF, FOB and CFR.

The stated lead time is 1 to 2 weeks depending on order requirements, with delivery directly from the factory. For a quotation, provide the required grade, quantity, packaging preference and destination. A buyer planning a full pallet order should also check whether the 500 to 600 kg pallet format suits the receiving and storage arrangements.

Pengze Technology (Shijiazhuang) Co., Ltd. can produce customized polymer powder according to customer requirements. A useful customization brief includes the application, target performance, raw materials, packaging needs and expected quantity.

For a putty or anti-crack mortar project, include the intended formulation and substrate in the brief so the proposed grade and sample can be evaluated in the right system. Before ordering, send the application, target performance, quantity, packaging preference and destination together.
