Introduction of products Redispersible Polymer Powder belongs to a kind of Coating Intermediates. At present, the widely used Redispersible Polymer Powder in the world are: vinyl acetate and ethylene copolymerization powder (VAC/E), ethylene and vinyl chloride and vinyl laurate terpolymerization powder (E/VC/VL), and vinyl acetate and vinyl and vinyl ester of advanced fatty acids terpolymerization powder (VAC/E/VeoVa), which are dominant in the whole market, especially the vinyl acetate and ethylene copolymerization powder VAC/E, which is the leading product in the global field and represents the technical characteristics of dispersible latex powder. The VAC/E copolymerization powder, VAC/E, is the global leader in the field and represents the technical characteristics of dispersible polymer powders. In terms of technical experience with Polymers applied to mortar modification, it is still the best technical solution: 1.One of the most used polymers in the world; 2.Have the most experience in the construction sector; 3.Can meet the required rheological properties of mortar (i.e., the required workability); 4.And other monomers of polymerization resin with low volatile organic compounds (VOC) and low irritant gas characteristics; 5.With excellent UV resistance and good heat resistance and long-term stability characteristics; 6.With high resistance to saponification properties; 7.With the widest glass transition temperature range (Tg); 8.With a relatively good combination of bonding, flexibility and mechanical properties; 9.With the longest how to produce stable quality products of chemical production experience and maintain storage stability; 10.Very easy and performance of the protective colloid (polyvinyl alcohol) combined.
Composition of Redispersible Polymer Powder
Redispersible Polymer Powder is usually a white powder, but a few have other colors. Its components include:
Polymer resin: located in the core part of the powder particles, and is the main component of the Redispersible Polymer Powder to play a role.
Additives (inside): work with the resin to modify it.
Additives (outside): To further expand the performance of the Redispersible Polymer Powder and add another material.
Protective colloid: a layer of hydrophilic material wrapped around the surface of Redispersible Polymer Powder particles, the majority of Redispersible Polymer Powder colloid is polyvinyl alcohol.
Anti-caking agent: fine mineral filler, mainly used to prevent the powder from caking during storage and transportation as well as to facilitate the flow of the powder.
Company information
The company's main import and export products include
（1）Organic Raw Materials：It has a wide range of uses, which can be divided into three aspects: first, it is used as a raw material for the production of polymer chemical products, i.e., monomers for polymerisation reactions; second, it is used as a raw material for other organic chemical industries, including fine chemical products; and third, it is used as a solvent, refrigerant, antifreeze, and gas adsorbent. Basic organic chemical industry is the basis for the development of the production of various organic chemical products, is the main component of the modern industrial structure.
（2）Intermediates：Intermediates are semi-finished products, which are products in the middle of the production of certain products, for example, to produce a product, which can be produced from intermediates to save costs.Intermediates are available from cyclic compounds such as benzene, naphthalene, anthracene, etc. by sulfonation, alkali fusion, nitration, reduction and other reactions.
