    Ammonium Polyphosphate APP

    Time:2018-04-09 22:16:12   
    Detailed introduction:
    Detailed introduction:


    Chemical formula: (NH4PO3)2
    Executive Standard: HG/T2770-1996

    Properties: Ammonium polyphosphate (APP), also known as polyammonium polyphosphate, is a high-quality, high-efficiency, non-toxic inorganic flame retardant. It is a necessary fire-retardant additive for various intumescent fire-retardant coatings and flame-retardant products. The high-polymeric long-chain ammonium polyphosphate produced by our company has a degree of polymerization of up to 50 and water solubility below 2G/100ML water.

    Technical indicators:


    Exterior  White powder
     P2O5                                              %    ≥68
     N content                                      %  ≥13-14
     pH value (1% aqueous solution)  4.5-6.5
    Average degree of polymerization n  ≥50
     Fineness  80,200,320,600 mesh


     1. The degree of polymerization phosphorus and nitrogen content is high, flame retardant effect is good;
     2. High degree of polymerization, low water solubility, low moisture absorption;
     3. The pH value is close to neutrality, thermal stability is good, compatibility is good;
     4. Very low toxicity (LD50>10g/kg), extremely safe in production and use.
     1. It is used to formulate a variety of high-efficiency intumescent fire-retardant coatings, which can be used in fire prevention treatment of high-rise buildings, ships, trains and cables;
     2. For flame retardant treatment of wood, plywood, fiberboard, paper, and fiber;
     3. The main flame-retardant additive used for plastic, resin, rubber intumescent flame retardant (IFR);
     4. Made of dry powder fire extinguishing agent for large areas such as forests, oil fields, and coal fields.
    Packing: 25kg bag, plastic outer knitting.
