About Shouxin

Polyacrylamide was first synthesized by Moureu via reaction of acryloyl chloride and ammonia at low temperature.

American Cyanamid Company filed the first patent for synthesizing polyacrylamide.

Polyacrylamide was entered commercial production in America. The first generation was sulfuric acid catalytic hydration technology, which was complex with high cost and low purity. The initial type was nonionic polyacrylamide, then anionic polyacrylamide was produced.

Shanghai Tianyuan Chemical Plant built the first polyacrylamide production unit to produce hydrosol products. It was not widely promoted and used due to the limitations in viscosity, fluidity and solubility of the products.

Dow Chemical (USA) and Mitsui Chemicals (Japan) developed the second-generation binary or ternary skeletal copper-catalyzed production technology. This technology is characterized by virtually no waste water, waste gas, or waste residue, is easy to industrialize, and contains a small amount of addition by-products.

Following the successful development of the cationic monomer acryloyloxyethyltrimethylammonium chloride (DAC) in Japan, cationic polyacrylamide was then put into production.

Academician Shen Yinchu developed the "10,000-ton microorganism catalysis method for producing acrylamide", which achieved the large-scale production of polyacrylamide.

The polyacrylamide market in China became highly active, with dozens of manufacturers having emerged. However, most of these manufacturers, constrained by limitations in formulation, production processes, development scope, and production costs, resulted in unstable product quality, relatively limited product models, and inadequate application compatibility.

Shouxin officially established itself as a global polyacrylamide brand with stable quality, to develop more variety, more stable, and more matched polyacrylamide models for global users.
