Oxyphosphonic Acid

1. Product Introduction

Oxyphosphonic Acid, app for short, is a nitrogen-containing phosphate, which is a white powder. Oxyphosphonic Acid can be divided into oligomeric, medium poly and high poly according to its degree of polymerization. The greater the degree of polymerization, the smaller the water solubility. Crystalline ammonium polyphosphate is water-insoluble and long-chain polyphosphate. There are five variants of type I to v. Among them, highly polymerized chemical Book crystalline type II ammonium polyphosphate has significant advantages in the field of polymer materials due to its good water insolubility, high decomposition temperature and good compatibility with polymer materials. Compared with halogen-containing flame retardants, crystalline ammonium polyphosphate II is a new type of high-efficiency inorganic flame retardant with the characteristics of low toxicity, low smoke and inorganic.
We can produce Oxyphosphonic Acid with high quality and reasonable price and supply in time, Our customers from Europe, USA, India and we are expecting become your long-term partner in china.

3.Product Feature And Application

Ammonium polyphosphate It is a mixture of ammonium orthophosphate and a variety of ammonium polyphosphate. The ammonium polyphosphate contained is mainly ammonium pyropolyphosphate. The appearance is white powder, close to neutral, and can be mixed with any other substance without chemical change. Short chain (n ≤ 20) app is water-soluble, while long chain (n > 20) app is insoluble in water. The solubility of industrial app in water is 1.3g/100ml (15 ℃) or 3.0g/100ml (25 ℃). The solubility increases significantly with the increase of temperature. App can be hydrolyzed. The hydrolysis rate changes with particle size, temperature and pH value. With the increase of temperature and pH value, the hydrolysis is accelerated. App has good thermal stability. The thermal decomposition temperature is above 250 ℃. Ammonia and water are released during decomposition and phosphoric acid is generated. It is completely decomposed at 700 ℃. The remaining 6% ~ 7% residue.
Ammonium polyphosphate is a polyphosphate containing N and P, abbreviated as app. According to the degree of polymerization, it can be divided into oligomer, medium polymer and high polymer. When the degree of polymerization is below 20, it is called oligomerization, which is water-soluble. When the degree of polymerization is above 50, it is called high polymerization, which can be used as a flame retardant. In the 1980s, considering the price, cost and other factors, oligomeric water-soluble app was mainly used in flame retardant cellulose materials such as paper and wood. Ammonium polyphosphate with high degree of polymerization is widely used in intumescent fire retardant coatings, polyethylene, polypropylene, polyurethane, epoxy resin, rubber products, fiberboard and dry powder fire extinguishing agents. It is a safe and efficient nitrogen phosphorus non halogen smoke suppression flame retardant.
