What is the meaning of SNF in chemistry?

SNF is the global leader in manufacturing polyacrylamides with a capacity of 1190 kt/y (active equivalent). These water-soluble polymers are used as flocculants and coagulants in solid/water separation to recycle water, rheology modifiers and friction reducers. SNF is one of the major chemical companies in France.

How are polyacrylamides made?

Polyacrylamide, or PAM, is an organic polymer formed from acrylamide sub-units. Initially, it is produced with a simple, repeating, linear chain structure, but can be modified to form highly structured, branched and cross-linked variants.

What is SNF used for?

SNF FOR CONSTRUCTION CHEMICALS It is recommended for construction of civil engineering concrete structures with concrete grade up to M40. This can be easily formulated to manufacture concrete Admixtures as per the customer need. Improves workability of concrete up to M40 grade at same W/C ration.

What is anionic polyacrylamide used for?

Anionic PAM is produced when acrylamide is polymerized with an anionic co- monomer. Water soluble PAMs have been used for decades to facilitate solid- liquid separations in wastewater and drinking water treatment, the pulp and paper industry, aquaculture, and many other industrial processes.

How are SNF polymers used in home care?

SNF has developed many high-performance polymers for home care, industrial, and institutional cleaning applications. SNF products improve germination, soil hydro-conductivity, irrigation efficiency, and soil water holding capacity. Our products can also reduce water and wind erosion, as well as crusting.

Why is SNF a leader in water soluble polymers?

As a leader in manufacturing and processing water-soluble polymers (based on polyacrylamide), SNF has developed a range of more than 1,000 products that help preserve our natural resources, encourage recycling, and improve efficiencies of industrial processes.

Which is the largest polyacrylamide producer in the world?

SNF is a privately-held, specialty chemical company based in the Rhone-Alpes region of France, with a long-standing presence on every continent. With 21 production sites in Europe, Asia, Australia, and America, with a production capacity of 1,235,000 tonnes, SNF has the largest polyacrylamide production capacity in the world.

How much water is in a polyacrylamide gel?

The water proportion varies from 20% to 40% of the final product, depending on the grade. Water is not considered as free; it is one of the poly- mer gel components. Polyacrylamides are high molecular weight water soluble or swellable polymers obtained from water soluble monomers (acrylamide, acrylic acid, adam-methyl chloride, etc.)
