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…
