Phosphonates have multifunctional qualities and excellent stability that can make the difference in the efficacy of your products. We believe it's important to offer you phosphonates, polymers and enzymes with proven properties. This makes them the perfect choice for a variety of industrial applications and for large-scale cleaning.

Discover the most important characteristics and applications of the BERFOS phosphonates and BERDIS polymers and enzymes for textile cleaning that FCI distributes.

Main properties

The ability of small quantities of scale inhibitors to keep large quantities of scalants in solution is known as the "Threshold Effect". Phosphonates are effective threshold scale inhibitors. This is due to the fact that phosphonates are adsorbed on the growth site of the scalant. This alters the growth pattern of the scale, reducing the speed of growth and distorting the crystals. The effectiveness of Berfos phosphonates as threshold inhibitors depends on conditions such as the type of scalant, water composition, supersaturation, temperature, pH and the type of phosphonate.

Sequestration (or chelation) is the ability of a substance to form a stable water-soluble complex with metal ions. The effectiveness of sequestration depends mainly on pH and the presence of other ions. The best comparison, however, can be made by the customer under actual use conditions.

De-flocculation or dispersion is the phenomenon that hinders the agglomeration of growing crystals and other particulates. Berfos phosphonates have this property and also have the added attribute of keeping such systems in a dispersed state over a wide area due to excellent hydrolytic stability.

Corrosion occurs when metal is attacked by oxygen in water. Berfos phosphonates in combination with zinc or phosphates and other corrosion inhibitors are highly effective in inhibiting corrosion. This combined action is much more effective than any single component on its own.

Berfos phosphonates are highly resistant to hydrolysis over a broad range of pH and temperature. This is very important for liquid formulations or where the process liquid is at elevated temperatures.

Chlorine is a common oxidiser and biocide widely used in a variety of applications. Berfos DHS and Berfos L 1000 offer greater chlorine stability than other phosphonates. Other phosphonates have relatively little stability compared to chlorine.

Key properties of BERDIS polymers

The properties of BERDIS polymers include threshold effect, crystal distortion, dispersion and chelation. These properties are enhanced and optimised for specific applications by controlling their molecular weight and use of appropriate monomers.
A wide range of applications ensures that each application is assisted by a state-of-the-art polymer that has been carefully evaluated to consistently deliver the best results.

The effect of BERDIS products is defined as the ability of a very small quantity of product to keep large quantities of scalants in solution. As a result, scale crystals form slowly and by the time they grow large enough to form a scale deposit, they are washed out of the system.

Dispersion or de-flocculation is the phenomenon that hinders agglomeration of particles. BERDIS polymers that are adsorbed on the surface of a particle impart a high negative charge to that particle. When two such particles come near each other, they mutually repel one another.

Crystal distortion is exhibited by all BERDIS polymers to a high degree. Precipitates that form in the presence of BERDIS polymers are highly distorted, fluffy and easily washed away by running water so that substrates prone to scale formation/incrustations are kept clean under extremely aggressive conditions.

Chelation is exhibited by all BERDIS polymers to a different degree. The polycarboxylic nature of these products is similar to that of amine carboxylates and these are therefore able to chelate hardness salts. Stability: all BERDIS polymers have high hydrolytic and thermal stability. They are also stable in the presence of strong oxidants such as chlorine, hydrogen peroxide, chlorine dioxide, etc. under normal use conditions and dosage levels.

Cleaning enzymes
Textile - Tanning

Enzymes have many industrial applications, which is why they are widely used in modern industry. Enzymes have not only enabled industrial processes to change; they also allow the consumer to formulate and use the finished product.

For example, using efficient enzymes in detergents means washing machines can run shorter washes at lower temperatures, considerably cutting energy use and pollution: in addition to reducing the human impact on water, fewer phosphates are used, which can build up and harm the environment

Detergents contain degradative enzymes that break down protease (BERPROT) and amylase (BERAMIL) proteins and lipase fats (BERZYM LIP), which are less aggressive on fabrics, unlike some chemical substances used in the past. In the textile sector, one interesting application is the stone-washing process used to give denim a used effect.

In the past pumice stone was used to make abrasions on the fabric or to lighten the colour. Nowadays cellulases (BERCEL) are used to do the same job in a faster and more controlled way, so much so that different hues can be created by using different concentrations of enzymes.

Catalase, laccase and peroxidase enzymes are also used to eliminate hydrogen peroxide and treat dyes in the bleaching and dyeing phases. In the tanning sector, lipase and protease enzymes facilitate hide and leather production processes such as maceration and degreasing. Similarly, other enzymes have been introduced into the paper industry in the bleaching and de-inking phases.
