Shandong Heast Building Material Co., Ltd is specialized in manufacture Redispersible Ploymer Powder which used on ceramic tile adhesive, Skim Coat, tile grout, wall putty, self leveling compound etc. Relies on strong financial strength we use full set industry-leading level production line and testing equipment from German. And established material research and development center. Our output 22000 ton. Heast has become one of the largest RDP manufacture in China.
RDP (Redispersible Polymer Powder/Redispersible Powder) or VAE is a water-soluble re-dispersible powder. It is a copolymer of ethylene and vinyl acetate. It d issolves in water easily and forms emulsion quickly , RDP could offer s trong adhesive and stretching force to i mprove the workability, flexibility and water-proofing of the materials
.Redispersible Polymer Powder is a kind of free-flowing white powder,which is spray-dryed by polymer emulsion and after subsequent treatment to keep the stability of powder appearance and character. The mainly application is in construction dry-mixed mortar,and have excellent performance in increasing the dry mortar cohesion,adhesion and flexibility.
Redispersible polymer powder product is water soluble redispersible powder, divided into ethylene/vinyl acetate copolymer, with polyvinyl alcohol as a protective colloid, spray drying white powder adhesive. This powder can be quickly dispersed into emulsion after contact with water, because of the redispersed polymer powder has high bonding capacity and unique properties, such as: water resistance, construction and heat insulation, therefore, their range of application is extremely wide.
Redispersible Polymer Powder is the most important binder in cement-based, gypsum-based dry powder materials. Redispersible Polymer Powder is a spray-dried powder of polymer emulsion. Redispersible Polymer Powder is re-emulsified with water and has the same properties as the original emulsion, that is a film can be formed after water evaporation. This film has high toughness, weather resistance and adhesion to a substrate. In addition, the latex powder with hydrophobic properties can improve the waterproof performance of the waterproof mortar.
