Physical and Chemical Properties | Ammonium polyphosphate can be divided into three types based on its degree of polymerization: low polymer, medium polymer, and high polymer. The higher the degree of polymerization, the smaller the water solubility. According to its structure, it can be divided into crystalline and amorphous types. Crystalline ammonium polyphosphate is water insoluble and long-chain polyphosphate. There are five variants from I to V type. |
Use | Inorganic additive flame retardant, used in the manufacture of flame retardant coatings, flame retardant plastics and flame retardant rubber products, etc. It is mainly used in intumescent fire retardant coatings and thermosetting resins (such as polyurethane rigid foam, UP resin, epoxy resin, etc.), and can also be used for flame retardant of fiber, wood and rubber products. Since the APP has a high molecular weight (n>1000) and high stability, it can also be used as a main active ingredient of intumescent flame retardant thermoplastics, especially in PP up to UL 94-Vo for the manufacture of electronic parts. |

colorless transparent viscous liquid. Deliquescence. It can be miscible with water and hydrolyzed to orthophosphoric acid without crystallization. Corrosive.
synthesis method: phosphoric acid and phosphorus pentoxide are heated for polymerization reaction, and hydrogen peroxide is added to remove iron ions in the solution. After purification, cooling and filtration are carried out to prepare a multi-phosphoric acid product.
is a Class II inorganic acid corrosion articles, risk code number: GB 8.1 class, 81505. Should be stored in a cool, ventilated warehouse, the container must be sealed. It is not allowed to be stored and mixed with alkaline substances, flammable substances, oxidants, etc. Transport should be protected from rain and sun. Light when loading and unloading
To prevent the leakage of the container rupture. White glass bottle with 500mL screw mouth, rubber cap sealing, 1kg net weight of each bottle. Coat the wooden box, between the box and the bottle with plastic ring pad, each box 12 vials. When there is a fire, it can be suppressed by sand and dry powder fire. Toxicity and protection: see industrial phosphoric acid.
