Key properties:

GD-APP101 is a fine-particle ammonium polyphosphate produced by a special method.The pruduct is largely insoluble in water and completely insoluble in organic solvent. It is white, non-hygroscopic and non-flammable,whose crystalline form is II,n>1000.

1,Low water solubility GD-APP101 has low water solubility which makes it useful in application where the product is exposed to high humidity conditions or water.

2,High phosphorus content GD-APP101 contains 72.5% phosphorus (as P2O5) which makes it a very effective fire retardant.

3,Nearly neutral PH-GD-APP101 can be neutralized or brought to the alkaline side by the addition of small amounts od ammonium hydroxide.

4,Non-halogen-GD-APP101 is a highly effective non-halogen fire retardant.


1,GD-APP101 can be used in intumescent coatings,paints.

2,GD-APP101 can be used in adhensive and sealants

3,GD-APP101 can be used in polyurethane foam: PU rigid, PU rigid integral skin foam, PU flexible.

4,GD-APP101 can be used in cellulose-containing material (paper, wood ).

5,GD-APP101 can be usd in thermoplastics (PP)

6,GD-APP101 can be used in casting resin based on epoxy resin and unsaturated PE resin
