Aluminium hypophosphite flame retardant decomposition temperature is high, insoluble in water, molecular weight phosphorus content reaches more than 40%, is a rare high phosphorus flame retardant in flame retardant monomer. The flame retardant mechanism of aluminum hypophosphite mainly includes condensation phase, meteorological flame retardant, generally with nitrogen, bromine components of flame retardants synergistic flame retardant, usually can be mixed with melamine cyanuric acid MCA, melamine hydrobromide MHB, biacu and other flame retardant effect. Aluminum hypophosphite production raw materials for sodium hypophosphate, aluminum sulfate, etc., the price and raw material price trend, supply and demand market and other factors.

Application description
1, with melamine hydrobromide MHB, bikwu compound can be used for polypropylene PPV-2 flame retardant, compound flame retardant add 0.5-1% can achieve flame retardant effect.
2, aluminum hypophosphite flame retardant can be used with melamine cyanurate MCA, melamine polyphosphate MPP for low smoke halogen-free cable material flame retardant. The flame retardant effect is better in the soft wire part of the data line.
3, can be used for polyester PBT flame retardant, formula, synergist is more critical, otherwise polyester products are easy to yellow, spots.
4, with other flame retardant compound can be used for potting adhesive flame retardant.
Storage and transportation conditions
25Kg/ bag, stored in ventilated cool dry warehouse, alkaline chemicals, flammable chemicals, oxidizing chemicals stored separately. Prevent violent, friction, impact extrusion, etc., otherwise it may catch fire.
Aluminum hypophosphite particle size distribution range, crystal type, surface modification, production process, temperature resistance and other indicators have a great impact on the flame retardant effect, which leads to different manufacturers of AHP flame retardants in the same material after the use of different effects. Aluminum hypophosphite flame retardants belong to class 4.1 dangerous chemicals, export needs to handle commodity inspection and dangerous package, there is no export tax rebate. Generally not suitable for nylon, polyurethane, rubber, paint, wood, paper field of flame retardant.
