Specifications

Sodium polyacrylate ,PAANa for short,with structural formula as [CH2CH(COONa)]n,is a kind of water-soluble resin with molecular weight of several millions.it is colorless or light yellow,solid,alkalescent,ionizable and corrosie.if the PH is approximately 4,it is likely to gelate;PH=2.5,it is likely to dissolve,which mostly occur in the sodium hydroxide solution,but in the calcium hydroxide and magnesium hydroxide solution it is likely to precipitate.it is nontoxic.molecular formula:[C3H3O2Na]n.macromolecular sodium polyacrylate is a kind of water precipitating agent and water-soluble macromolecular material developed with the adoption of internationally advanced technology.which can enable the viscosity increase of other aqueous solution or dispersion. therefore.the two major functions of this product are efficient flocculation and efficient thickening.

Efficient flocculation----with charge ,the macromolecular sodium polyacrylate is capable of neutralizing ,adsorbing and bridging the suspended particles in water and enables them to agglomerate together .in this way,this product is well-performed in precipitation ,clarification ,purification ,etc.(Notes :the proper dosage will achieve a proper effect of flocculation .if too much added .it will lead to dispersion.)

Efficient thickening----on one hand ,the macromolecular sodium polyacrylate resorts to its viscosity to increases the viscosity of water phase which has a certain functional relation to the concentration of polymer ,on the other hand, it reacts with the dispersed phase and other macromolecular compounds in the water ,which makes the polymerthicker. Therefore,as a kind of thickening agent ,this produce can be widely applied to the occasions in which the viscosity of the aqueous solution or aqueous dipersion system should be increased.

Macromolecular sodium polyacrylate is a kind of macromlecular material and important chemical product with entirely new functions ,which is characterized by its stability in varying temperature, it’s fixationg of metallic ions and its prevention from the negative effect caused by the metallic ions .As a kind of multi-purposed surfactant, it is soluble in the mediums such as cold water,mild water,glycerin,propylene glycol, etc

  if you don't used it before you can tell me more about you useage so that i can tell me which model can meet you need

we can send you some sample to you if you need

  if you have any question you can contract me
