About us

We provide superabsorbent polymers

These products are in the form of powders, water-soluble sachets, granules, and tablets.

Permanent stock of superabsorbent products

We must be very reactive as most of our customers are in a hurry!

For that, we have a permanent stock, our partnerships with leading producers of superabsorbent polymers allow us to guarantee a constant supply of quality products.

Do you know the superabsorbent products?

Superabsorbent products exist on the market for over 50 years!

Originally developed in the USA for the purposes of agriculture and then quickly for the needs of the hygiene industry such as diapers.

They were able to replace natural products, such as peat moss, because the latter being a non-renewable source, was doomed to disappear. Various biosourcing initiatives in commodities having largely failed because of their poor performance, only polymers such as sodium polyacrylate and polyacrylamide are present on the market nowadays. World production is about 2 million tons today.

How do superabsorbent polymers work?

The polymer is composed of a long carbon chain regularly interconnected by bridges called « crosslinkers » channels, thus forming a network. Once the water is in contact with one of these channels, it is drawn into the molecule by osmosis. Water progresses rapidly within the network to be stored therein. Conversely, when the medium dries, the polymer then releases its water more or less rapidly.

Several parameters can affect the product: salt, temperature, UV … The life of the product, once hydrated, is a few days to several years depending on the type of polymer composition.

Why are there any variations in absorption according to the liquid level?

The first element is polymer chemistry itself. Depending on the amount used of the crosslinking, the polymer will absorb more or less liquid. For example, if the polymer is cross-linked, the network is thus narrowed and the stability over time is enhanced but the capacity is decreased. On the other hand, the less there is crosslinking the bigger the network is, so the volume of absorption is increased but stability is reduced.

Are super absorbent products degradable?

Once destabilized, when they have lost all of their effectiveness, « oligomers » (fractions of polymers) are formed. These elements, under thermal and bacterial action, mineralize at 8% the first year and then 3% per year in the ground, so about 30 years for total soil mineralization and digestion.

Recent studies on sodium polyacrylate demonstrate the biodegradable faculties of superabsorbent polymers under certain conditions.
