Our solutions for industrial applications -
enhancing products and processes with versatile phosphorus chemistry

From closing rings in chemicals to improve metalworking and many other industries

Phosphorus compounds can not only be used as flame retardants but also in many other industrial applications. They serve as vital chemicals for making products like pharmaceuticals, vitamins, catalysts and glass. And, in the form of phosphate esters, they can enhance anything from metalworking fluids and industrial cleaners to laundry detergents and paints.

We offer high-quality polyphosphoric acids and phosphorus pentoxide for chemical and other industrial uses, and we turn these compounds into our versatile range of Hordaphos® phosphoric acid esters. In addition, we provide stabilized red phosphorus for pyrotechnics.

Hordaphos® – our multifunctional product range for manifold uses

By varying their chemistries, we have tailored the phosphate esters of our Hordaphos® range to many industrial uses. They can help to cool and lubricate machinery in metalworking while also inhibiting corrosion. And they are strongly acidic yet non-corrosive to metal when fighting scale and organic deposits in mining, food processing and other industries.

With their high adaptability, our Hordaphos® products can also be used for controlling foam and static in detergents or enhancing the dispersion and color strength of pigments. Just tell us the properties you’re looking for – and we’ll surely find a solution.

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.
