  Production Process  _____________________________________________

Ethylene-vinyl acetate rubber powder (VAE-RDP) is made of vinyl acetate/ethylene copolymer emulsion (EVA emulsion) modified by adding water-soluble protective colloid (polyvinyl alcohol usually PVA) and spray-dried, using water as the medium Can be re-formed into an emulsion, a powder with redispersibility.


  Physical And Chemical Properties  _________________________________

(1) Redispersible polymer powder is easily soluble in water and easy to form emulsion.

(2) Redispersible polymer powder has strong cohesive force and good tensile force.

(3) Redispersible polymer powder can improve the processability, flexibility and impermeability of materials.

(4) Redispersible polymer powder can improve the cohesion of the mortar, increase the concentration and anti-sagging.

(5) Redispersible polymer powder can improve the flexibility of the mortar and extend the open time.
