Polyacrylamide - Truth In Aging
It is used in cosmetics and beauty products in two different forms, either as a soft gel in its cross-linked form, which has highly water-absorbent properties, or in its straight-chain form, as a thickener and suspending agent. It has also been used recently as an active ingredient in the subdermal wrinkle filler, Aquamid.

Polyacrylamide Uses
Polyacrylamide for Edge-water Encroachment Use(PAM As Oil-displacing Agent) When the oil field is exploited in the petroleum tertiary recovery, if the single injection drive is applied, its fluidity is higher than the crude move, as a result, it lowers the spread efficiency and increases the water consumption, and the water content of the crude

The Application of Water Retaining Agent - Sinofloc Chemical
The water absorption principle of water retaining agent is the same as the general SAP. It is formed by the expansion of tension (which is produced in water the polymer electrolyte molecule chain amide base and/or carboxyl group) and the expansion of tension (which is produced because of the restriction molecular chain of intersection point) interacting each other.

Polyacrylamide
Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.In the cross-linked form, the possibility of the monomer being present is reduced even further.

Polyacrylamide (PAM) and Enhanced Oil - Sinofloc Chemical
For oil extraction applications, polyacrylamide is used to increase the viscosity of water to improve the effectiveness of the water flooding process. A polymer solution is more viscous than brine without polymer. In a flooding application, the increased viscosity will alter the mobility ratio between the injected fluid and the reservoir oil.
