Zhejiang Longyou GD Chemical Industry GD-APP101

Zhejiang Longyou GD Chemical Industry GD-APP101 equivalent to Clariant GmbH's Exolit AP 422, 423 and Budenheim FR Cros 484. 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.

    Key Properties
    • 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.
    • High phosphorus content GD-APP101 contains 72.5% phosphorus (as P2O5) which makes it a very effective fire retardant.
    • Nearly neutral PH-GD-APP101 can be neutralized or brought to the alkaline side by the addition of small amounts od ammonium hydroxide.
    • Non-halogen GD-APP101 is a highly effective non-halogen fire retardant.
