Piperazine pyrophosphate (PAPP) is a new environmentally friendly flame retardant. The domestic market is currently in the promotion stage.

Piperazine pyrophosphate (PAPP), also known as piperazine polyphosphate (focused piperazine phosphate), is a halogen-free, environmentally friendly intumescent flame retardant designed with phosphorus and nitrogen as the main flame retardant element. The appearance of piperazine pyrophosphate is white or off-white crystal powder. It has the characteristics of high carbon-forming efficiency, good thermal stability, low smoke and non-toxicity, light aging resistance, and low hygroscopicity. It can be used in polypropylene (PP), polyethylene ( Flame-retardant products such as PE), polyurethane (PU), acrylonitrile-butadiene-styrene (ABS), and epoxy resin (EP) have huge market development potential in the future.

Flame retardants can be divided into organic halogen series, phosphorus series, inorganic series, etc. At this stage, the global flame retardant market demand has reached about 3.2 million tons/year, of which halogen flame retardant consumption accounts for 20%. In recent years, as environmental protection supervision has become increasingly strict, the market demand for flame retardants with environmental protection, low toxicity, and high efficiency has increased, and the market consumption of halogen flame retardants has declined. Against this background, the piperazine pyrophosphate flame retardant market has Increased attention.

According to the “2021-2026 China Piperazine Pyrophosphate Flame Retardant Industry Market In-depth Research and Development Prospects Forecast Report》 shows that from 2016 to 2020, the global market consumption of piperazine pyrophosphate flame retardant has continued to grow. By 2020, market consumption has reached about 9,700 tons. As a new flame retardant product, the piperazine pyrophosphate flame retardant market is still in the early stages of development, and its proportion in the flame retardant market is also small. The future market development potential is huge.

The downstream application structure of piperazine pyrophosphate is relatively simple. It is mainly used in flame-retardant polypropylene products, accounting for 90% of the applications. The preparation methods of piperazine diphosphate include piperazine diphosphate condensation method, metathesis precipitation method and phosphorus pentoxide method. Among them, piperazine diphosphate condensation method is widely used due to its high yield. This method first synthesizes piperazine diphosphate. The intermediate, piperazine diphosphate, is then condensed to piperazine pyrophosphate via dehydration.

From the production side, Japan’s Adico Co., Ltd. is the first company to start commercial production of piperazine pyrophosphate flame retardants globally. In the domestic market, the main manufacturers of piperazine pyrophosphate flame retardants include Shanghai Chemical Industry Research Institute, Sichuan Refining and Chemical Research Institute, Chongqing Kejufu New Materials, Connold, etc. Compared with Europe, the United States and Japan, the research on piperazine pyrophosphate flame retardants in my country started relatively late, and only started related research in 2010. At present, the market of piperazine pyrophosphate flame retardants in my country is in the promotion stage. Due to the small number of production companies , the market concentration of piperazine pyrophosphate flame retardants is relatively high, but due to the short development time, there is currently no leading company in the industry.

Industry analysts said that my country’s piperazine pyrophosphate flame retardant market is still in the promotion stage. With the increase in the number of companies involved, The market size of piperazine pyrophosphate flame retardant will continue to expand. At the same time, as environmental protection supervision becomes increasingly strict, environmentally friendly, low-toxic, and efficient flame retardants will become the main development direction of the flame retardant industry in the future. As a new flame retardant, piperazine pyrophosphate flame retardant has advantages in environmental protection, cost, performance, etc. Outstanding, the future market development potential is huge.
