Our Hordaphos® line and phosphorus chemicals

P-BASED QUALITY AND PERFORMANCE
FOR A WIDE PANOPLY OF USES

Highly reactive
AND EXTREMELY USEFUL IN MANY COMBINATIONS

Phosphorus is one of the Earth’s most reactive and, if skillfully combined, most versatile elements. At our site in Knapsack, Germany, we use it to make high-quality phosphorus chemicals as well as the tailored phosphoric acid esters of our Hordaphos® line.

First-rate phosphorus chemicals and phosphate ester innovations

Phosphorus has a long history of use at our German site, which is among the largest European sources for some of its derivatives. From white phosphorus, we produce stabilized grades of red phosphorus for advanced pyrotechnics as well as high-quality polyphosphoric acids and phosphorus pentoxide. These inorganic compounds are widely used in the production of surfactants, colorants, pharmaceuticals and vitamins, and they also serve as raw materials for our own organophosphorus innovations.

By carefully controlling reaction partners and conditions, we create tailor-made phosphoric acid esters for a wide array of applications. Marketed under our well-known Hordaphos® brand, these versatile phosphate esters are used as powerfully acidic yet non-corrosive ingredients in cleaning products, antistatic and anti-foaming agents in laundry detergents, and multifunctional additives in inks, paints and coatings. By tweaking the length of their alkyl chains, they can be customized for these as well as many other applications.

FIRST-RATE PRODUCTS AND PHOSPHORUS PERFORMANCE

  • Phosphorus pentoxide (P2O5)

    Phosphorus pentoxide is a white, microcrystalline, light weight powder which is produced by the combustion of elemental phosphorus in an excess of oxygen. Phosphorus pentoxide is the anhydride of orthophosphoric acid, H3PO4. It is very hygroscopic and is converted by water to H3PO4 via intermediates. The reaction with water is very vigorous and proceeds with the evolution of a large amount of heat. Due to its highly hygroscopic and microcrystalline character, the capability of flowing of P2O5 may vary in a certain range. Furthermore, the formation of soft agglomerates, which come apart under slight pressure, is not preventable.

  • Red Phosphorus HB 600

    Red Phosphorus HB 600 is a stabilized and microencapsulatedgrade of red phosphorus, delivered as a wet filter cake with 9-25% moisture (mean value for all drums of one delivery max. 20% moisture). It has a good oxidation and thermal stability. Red Phosphorus HB 600 is a brownish-red powder that is insoluble in water and organic solvents.

  • Hordaphos® MDGB

    Hordaphos MDGB is an effective corrosion inhibitor for acidic aqueous systems, e.g. for cleaners for the food processing industry. It is a clear, colorless to yellowish liquid with an ester-like odor. The product is not in all ratios clearly soluble in water.For more details see our Video about Hordaphos.
