Our core product, RDP redispersible polymer powder, can provide you with higher quality products and can also be customized to meet your needs for different viscosities.Shijiazhuang Qingquan Cellulose Co., Ltd. is a cellulose manufacturer from China.
Dispersible polymer powder (RDP) is a key additive that provides bonding strength and flexibility.
Main types: Made by spray drying of polymer emulsion, common ones include vinyl acetate/ethylene copolymer (VAE), acrylic esters, etc.
Main Applications:
Improving Bond Strength: Forming a polymer film within the mortar, it interweaves with cement hydration products, significantly enhancing the bond between the mortar and the substrate (such as concrete or tile). This is a core component of tile adhesives and insulation system bonding mortars.
Increased flexibility: This allows the mortar to deform to a certain degree, allowing it to withstand stress caused by temperature changes and slight creep of the base layer, thus preventing cracking (cracking resistance).
Increased cohesive strength: This makes the mortar stronger and more wear-resistant.
Reduced elastic modulus: This makes the mortar "softer," allowing it to better match hard substrates (such as concrete) and achieve more uniform stress distribution.
