At the moment, the main Redispersible Polymer Powder in the market are: VAC/E, E/VC/VL, V AC/E/VeoVa, V/AC/V eo Va, A/S, V AC/A/V eo Va, PV AC, SBR, other binary and ternary copolymer rubber powders, other formula rubber powders added with functional additives, and other formula rubber powders with functional additives and more than one type of rubber powder.
The first three dispersible polymer powders account for the vast majority(over 80%) of the global market. In particular, the first vinyl acetate and ethylene copolymer rubber powder has a leading position in the global field and represents the technical characteristics of the dispersible polymer powder.
From the technical experience of the polymer applied to the mortar modification, vinyl acetate and ethylene copolymer resin are still the best technical solutions for the following reasons:
- vinyl acetate and ethylene copolymer resin are one of the most used polymers in the world;
- vinyl acetate and ethylene copolymer resin have the most experience in the construction field;
- vinyl acetate and ethylene copolymer resin can meet all the rheological properties of the mortar(the required workability);
- vinyl acetate and ethylene copolymer or with other monomeric polyresins have low organic volatiles and low irritating odor;
- vinyl acetate and ethylene copolymer resin have excellent UV resistance and good heat resistance and long-term stability;
- vinyl acetate and ethylene copolymer resin have high saponification resistance(due to the unsaponifiability of ethylene);
- vinyl acetate and ethylene copolymer resin have the widest range of glass transition temperatures;
- vinyl acetate and ethylene copolymer resin have relatively good comprehensive adhesion, flexibility and mechanical properties;
- experience in chemical production with the most stable quality products and maintaining storage stability;
- vinyl acetate and ethylene copolymer resin are easy to combine with protective colloids with excellent performance;
