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.
Polyacrylamide For Water Treatment

Polyacrylamide For Paper Making Industry Application
1. Dispersing Agent for Paper Making
In paper making process, PAM is used as dispersing agent to prevent fiber agglomeration and improve paper evenness. Our product can be dissolved within 60 minutes. Low addition amount can promote the good dispersion of paper fiber and excellent paper forming effect, improving the evenness of pulp and the softness of paper, and increasing the strength of paper. It is suitable for toilet paper, napkin and other daily used paper.

2. Retention and Filter Agent for Paper Making
It can improve the retention rate of fiber, filler and other chemicals, bringing clean and stable wet chemical environment, saving the consumption of pulp and chemicals, reducing production costs, and improving paper quality and paper machine production efficiency. Good retention and filter agent is the prerequisite and necessary factor to ensure the smooth operation of the paper machine and good paper quality. High molecular weight polyacrylamide is more widely suitable for different PH value. (PH range 4-10)
