????? Product Overview
This product is a high molecular weight anionic water-soluble polymer, divided into four grades as the molecular weight increases. It has good solubility in water and lower filter factor. Used for tertiary oil recovery polymer flooding, it can effectively improve the viscosity of the injected water, reduce water phase permeability, reduce the oil-water viscosity differences, improve the mobility ratio and expand the volume of injected water so as to enhance oil recovery.

????? Product Characteristics
High molecular weight, up to more than 20 million, so the viscous effect is remarkable.
Good solubleness, uniform distribution, easy to inject and good transmissibility.
Good shear stability and heat and salt resistance.
Low adsorption of reservoir, small stock.
High economic benefit in recovery operation.
Product Feature
Polyacrylamide is easy to absorb water. The water absorption speed differs with derivatives ionic character difference. Polyacrylamide is soluble in water, and also soluble in organic solvents such as acetic acid, ethylene glycol, glycerin and amine. It resolves in long-time heating. The decomposition temperature is above 120℃. Under anaerobic conditions, it carbonizes to black powder at 210 ℃.
As required, non-ionic polyacrylamide can be processed into anionic, cationic and mixed ion products.
