Characteristic

Ammonium polyphosphate (APP) is avirulent insipidity, and do not produce the corrosive gas, hot high stability, is a fine performance non-brine flame retardants. Mainly used as flame retardant. Product P and N content high, thermal stability and chemical stability performance is good, water-soluble and suction wet sex small, product close to neutral, low toxicity (LD P 10g/kg). APP in polyurethane hard vesicles has a high flame retardants, dimension stability, heat-resistance and resistance to hydrolysis. Ammonium polyphosphate have expanded flame retardant function. APP in addition to apply to the rigid polyurethane foam plastics and polyester soft polyurethane foam plastics outside, also applies to other resin, adhesives and coatings.

It can be divided according to the degree of polymerization size, low, gather together three high, The degree of polymerization is larger, water-soluble small, According to the structure can be divided into the crystalline form, and functional crystal together for water soluble ammonium phosphate, and there are gathered the v-shaped five.

Application

Mainly used in fire coatings, plastic, rubber, wood, paper and other materials of flame retardants, Can a dual compound fertilizer, as high feed additives, liquid detergents, adhesive, ion exchange.

Storage and Packing

Plastic-woven sack with polythene inner bag, Net weight 25kg　or 500, 600 kilograms of big bag (may be based on customer needs)
