RFR-APP-3

General Description and Use:
Chemical name: Ammonium polyphosphate
Molecular Formula: (NH4PO3)n
Cas No.68333-79-9
 
APP-3 is a product based on ammonium polyphosphate. The crystal modification is phase II. It is manufactured from APP-1 by micro-encapsulation with melamine.
APP-3 is a fine-particle white powder with very low solubility in water, even at elevated temperatures. It is completely insoluble in organic solvents. The product is non-hygroscopic and non-flammable.
APP-3 differs from APP-1 in the following properties:
– marked reduction in water
– soluble constituents
– even lower viscosity in aqueous suspension
– lower heat stability in the temperature range > 300 °C
– improved powder flowability.
Main use in Plastic(PP,PE,PA,PVC,PBT),PU, Rubber, Paint, Textiles coating…
