Amphoteric polyacrylamide

manufactured from cationic monomer, acrylamide monomer, and anionic monomer

The product is manufactured from cationic monomer, acrylamide monomer, and anionic monomer. It’s a kind of polymer with both cationic and anionic on its molecule chain.

Product Code	Cationic degree(%)	Anionic degree(%)	Solids Content(%)	Residual monomer(%)	Insoluble(%)	Size of the particles	Dissolving Time(h)
YP — 5000	5-10	10-25	≥ 88	≤ 0.05	≤ 0.2	Particle size greater than 1.0mm ≤5% Particle size less than 0.2mm ≤5%	<2

Notes:1.The concentration level of YP-5000 series products is generally 0.05-0.1% and its dissolution time under normal temperature is no more than two hours. 2. The product is packaged in 25kgs bags with three layers of paper and a layer of plastic. Special package can also be arranged based on customer requirement. Application: 1.Water-plugging mixing and analyzing product in oilfield: the wide use of oilfield has displayed that the character of the polymer is beyond other water-plugging products. 2. As a new type of water treatment flocculation agent, YP-2000 has the function of zwitterions. It can fulfill the combination of negative and positive ions. Particularlly in the areas where the conditions are cmplex, This product is very convenient and efficient . 3.Mud dehydration: the zwitterion polyacrylamide as specific mud dehydration,after dehydrating test and use toward various mud, are both more efficient than single-ion polyacrylamide
