About Us

Polyacrylamide was first created by Moureu through reaction of acryloyl chloride and ammonia under low temperature.

American Cyanamid Company published the first patent of synthetic polyacrylamide.

Polyacrylamide was put into industrial production in America. The first generation was sulfuric acid catalytic hydration technology. It was complex with high cost and low purity. The first type was nonionic polyacrylamide, then anionic polyacrylamide was developed.

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

Dow in America and Mitsui in Japan developed the second generation technology-binary or ternary skeleton copper catalyzing, almost no waste water, gas or residue,easy to achieve industrialization,containing small amount of additive reactants.

Cationic monomer DAC was successfully developed in Japan. Cationic polyacrylamide was then put into production.

Academician Yinchu Shen developed the "10,000-ton acrylamide production technology by microbial method.", which achieved the large-scale production of polyacrylamide.

Polyacrylamide market in China became more active. There were dozens of manufacturers but products were lack of variety and quality was not stable due to the restrictions of formulation, manufacturing process, development field and production costs.

Shouxin officially began its way as a global polyacrylamide brand with stable quality, to develop more, more stable and more matched polyacrylamide models for global users。

Shouxin was established focusing on water treatment chemical materials.

Transited to specialize in polyacrylamide,Set up professional R&D, quality control, sales and after-sales teams.

Cooperated with China’s largest paper-making company Nine Dragons Paper.

Optimized the whole system of raw material control, formula development, manufacturing process supervision and double inspection of incoming and outgoing goods with strictly selected partners.

Number of listed company and top 500 company customers exceeded 100,won the Best Stable Quality Award from the National Functional Polymer Industry Association.

The annual throughput of products exceeds 60,000 tons,awarded the "Chairman Unit" by the most authoritative official organization in the industry.
