PP polypropylene used flame retardant Ammonium Polyphosphate factory supply
Product name: Ammonium Polyphosphate
CAS No.: 68333-79-9
Ammonium polyphosphate is an important chemical substance with many uses and characteristics. The chemical formula for ammonium polyphosphate is (NH4PO3) n.
It is a white powder with high polymerity (n ≥ 1000), almost insoluble in water, pH 5.5-7.0, moisture content ≤ 0.25%, thermal decomposition temperature ≥ 280 ° C, density of about 1.9 g / cm3, accumulation density of around 0.7 g ⁄ cm3.
The phosphorus content of ammonium polyphosphate is 30% -32% and the nitrogen content is 14% -16%.
Use1. Flame retardant:
Ammonium polyphosphate is an efficient non-halogenated flame retardant with the advantages of being environmentally friendly, having a small amount of addition and having few effects on mechanical properties. The amount of flue generated during combustion is extremely low, does not produce hydrogen halide, and is suitable for flame retardant treatment of various polymer materials.
Use2. Fertilizer:
As a new fertilizer, ammonium polyphosphate is widely used in the field of chemical fertilizer. It is often used as the basic phosphate fertilizer of high concentration liquid compound or mixed fertilizer. Its low nitrogen and high phosphorus properties give it an important role in agriculture.
Use3. Scientific research:
Ammonium polyphosphate is used as a buffer in biochemical and physiological experiments and also plays a key role in cell culture preparation. In addition, it is used as a reagent for the synthesis of organic compounds and as a catalyst in polymer production.
