Piperazine pyrophosphate (PAPP), also known as piperazine polyphosphate (piperazine focusing phosphate), is a halogen-free environment-friendly intumescent flame retardant designed with phosphorus and nitrogen as the main flame retardant element. The appearance of piperazine pyrophosphate is white or almost white crystalline powder. It has high charring efficiency, good thermal stability, low smoke and non-toxic, light aging resistance, low moisture absorption and other characteristics. It can be used for flame retardant products such as polypropylene (PP), polyethylene (PE), polyurethane (PU), acrylonitrile-butadiene-styrene (ABS), epoxy resin (EP), and has great 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 market demand for flame retardants has reached about 3.2 million tons/year, of which the consumption of halogen flame retardants accounts for 20%. In recent years, with the increasingly strict environmental supervision, the market demand for flame retardants with environmental protection, low toxicity, high efficiency and other characteristics has increased, and the market consumption of halogenated flame retardants has declined. In this context, the market attention of piperazine pyrophosphate flame retardant has increased.
According to the in-depth market research and development prospect forecast report of piperazine pyrophosphate flame retardant industry in China from 2021-2026, the global market consumption of piperazine pyrophosphate flame retardant continued to grow in 2016-2020, and reached about 9700 tons by 2020. As a new type of flame retardant product, the market of piperazine pyrophosphate flame retardant is still in the early stage of development, its share in the flame retardant market is also small, and its future market development potential is huge.
The downstream application structure of piperazine pyrophosphate is relatively simple, mainly used in flame retardant polypropylene products, accounting for 90%. The preparation methods of piperazine diphosphate include piperazine diphosphate condensation method, double decomposition precipitation method and phosphorus pentoxide method, among which the piperazine diphosphate condensation method is widely used due to its high yield. This method is to first synthesize the intermediate of piperazine diphosphate, and then synthesize piperazine diphosphate through dehydration and condensation.
At present, the market of piperazine pyrophosphate flame retardant in China is still in the promotion stage. With the increase of the number of enterprises, the market scale of piperazine pyrophosphate flame retardant will continue to expand. At the same time, with the increasingly strict environmental protection supervision, 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 type of flame retardant, piperazine pyrophosphate flame retardant has outstanding advantages in environmental protection, cost, performance and other aspects, and has great market development potential in the future.
