Polyacrylamide 90%
Polyacrylamide (PAM) is a linear water-soluble polymer, the general term for acrylamide homopolymers or copolymers and modified products, the most widely used variety of water-soluble polymers, and known as “Auxiliary agent for all industries”. Based on the structure of polyacrylamide, it can be divided into non-ionic, anionic and cationic polyacrylamide. According to the molecular weight of polyacrylamide, it can be divided into ultra-low molecular weight, low molecular weight, medium molecular weight, high molecular weight and ultra-high molecular weight. Our company has developed a full range of polyacrylamide products through cooperation with scientific institutions.Our PAM products includes oil exploitation series, non-ionic series, anion series, cationic series. The molecular weight range of polyacrylamide is 500 thousand ~ 30 million. Widely used in various fields such as water treatment, oil exploitation, paper-making, textiles, mineral processing, coal washing, sand washing, soil conditioner, etc.
