Phosphates are basically compounds of phosphorus and oxygen that occur in many forms and are usually combined with other elements. These compounds are extensively used as flame-retardants for textiles, plastics, coatings, paper, sealants and mastics. We offer a wide range of phosphate compounds such as Di-Ammonium Phosphate.

Production :
Ammonium phosphate first became available in the 1960s, and DAP rapidly became the most popular in this class of products. It is formulated in a controlled reaction of phosphoric acid with ammonia, where the hot slurry is then cooled, granulated and sieved. DAP handles and stores well. The standard nutrient grade of DAP is relatively high.

The inputs required to produce one ton of DAP fertilizer are approximately 1.5 to 2 tons of phosphate rock, 0.4 tons of sulphur (S) to dissolve the rock, and 0.2 tons of ammonia. Changes in the supply or price of any of these inputs will impact DAP prices and availability. The high nutrient content of DAP helps reduce handling, freight and application costs. DAP is produced in many locations in the world and is a widely traded fertilizer commodity.

  • DAP also acts as a fire retardant. For example, a mixture of DAP and other ingredients can be spread in advance of a fire to prevent a forest from burning. It then becomes a nutrient source after the danger of fire has passed.
  • DAP is used in various industrial processessuch as metal finishing.
  • It is commonly added to wine to sustain yeast fermentation and to milk to produce cheese cultures.
