AMMONIUM POLY PHOSPHATE  is a fine-particle ammonium polyphosphate (phase II) produced by a special method. The product is largely insoluble in water and completely insoluble in organic solvents. It is colourless, non-hygroscopic and non-flammable.

• Non-halogenated flame retardant with favorable environmental and health profile.
• Greatly reduced water solubility, low viscosity in aqueous suspension, very low acid number.
• Particularly suitable as an ”acid donor” for intumescent coatings thanks to its low water solubility. Steel structures coated with intumescent paints can meet the requirements of fire resistance classes specified in EN, DIN, BS, ASTM and others.
• Their application on wood or plastics enables these materials to qualify for Building Material Class B (DIN EN 13501-1).
• Excellent flame-retardant effect in cellulose-containing materials such as paper and wood products. With chipboard products, the DIN EN 13501-1 classification can be achieved by adding 15-20 % AMMONIUM POLY PHOSPHATE
• Excellent flame-retardant effect in polyolefin based wood plastic composites (WPC) with high wood contents (> 50%) at a dosage of 10-15% AMMONIUM POLY PHOSPHATE 
• Imparts a good flame-retardant effect to adhesives and sealants when it is incorporated into the base formulation at the rate of 10-20%.
• Efficient non-halogenated alternative for conventional flame retardants (e.g. TCPP) in various PUR applications, with minimum impact on reaction profiles and material properties. 
• In the case of thermosets like epoxy resins and unsaturated polyester resins, AMMONIUM POLY PHOSPHATE paves the way for the production of lightweight components with low solids content.
• AMMONIUM POLY PHOSPHATE can be used in transport applications to obtain good fire, smoke and toxicity results.
• (Bio-)degradable by breaking down to naturally occurring phosphate and ammonia.
