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.
Applications:
1,GD-APP101 can be used in intumescent coatings,paints,adhensive and sealants,polyurethane foam: PU rigid, PU rigid integral skin foam, PU flexible,cellulose-containing material ,thermoplastics ,casting resin based on epoxy resin and unsaturated PE resin. |
