Ammonium Polyphosphate(APP-I)

Product Description

Molecular Formula: (NH4) (n*2)PnO(3n*1) CAS NO.: *********9 Ref. Standard: HG/T********6 production capacity: ***0 t/a Properties: White fine powder. It is an excellent, high-efficiency and nontoxic inorganic flame retardant, used as the necessary flameproof additive for all kinds of expanding-type flameproof coating and flameproof products. When *0≤n≤*0, it’s soluble, when n>*0, it’s relatively insoluble. We can supply APP with n>*0, and the solubility in water is lower than 2g/**0ml water. Technical Specifications: No. Index APP*1 1 P2O5 content %≥ *8 2 N Content %≥ ****4 3 Average polymerization degree (n) ≥ *****0 4 pH value (1% aqueous solution) (*0% aqueous suspension) 4.**6.5 5 Particle size ******0mesh Features: 1. high content of phosphorus and nitrogen, good flameproof effect; 2. high polymerization degree, low solubility in water and low hygroscopicity; 3. PH is near to neutral, good heat stability and good compatibleness; 4. very low toxicity (LD*0>*0g/kg), very safe during production and use; Application: 1. used to prepare many kinds of high-efficiency expanding-type flameproof coating, the flameproof treatment for multistory building, ships, trains, cables, etc. 2. used in the flameproof treatment for woods, plywood, fiberboard, papers, fibers, etc. 3. used as the main flameproof additive for expanding-type flame retardant used in plastic, resin, rubber, etc. 4. made into powder extinguishing agent to be used in large-area outfire for forest, oil field and coal field, etc. Packaging: packed in plastic woven bag with PE lining, *5kgs/bag. Stored in ventilated and dry place.
