In the pursuit of safer and more sustainable materials, the chemical industry is increasingly turning towards halogen-free flame retardants. Among these, Ammonium Polyphosphate (APP) stands out as a powerful and versatile solution. As a leading manufacturer and supplier of advanced chemical additives, we at NINGBO INNO PHARMCHEM CO.,LTD. are committed to providing innovative solutions that meet the evolving demands for fire safety and environmental responsibility.

Traditional flame retardants often contain halogens, which can release toxic and corrosive gases when exposed to fire. This poses significant health risks and environmental concerns. Halogen-free alternatives, such as APP, offer a compelling solution by achieving excellent flame retardancy through mechanisms that do not involve halogenated compounds. This shift is driven by stricter regulations and a growing consumer demand for safer products.

Ammonium Polyphosphate is an inorganic salt of polyphosphoric acid and ammonia. Its effectiveness as a flame retardant stems from its phosphorus and nitrogen content, which work synergistically. When subjected to heat, APP decomposes to form phosphoric acid and ammonia. The phosphoric acid acts as a catalyst, promoting the dehydration and carbonization of the polymer matrix, thereby forming a protective char layer. This char layer insulates the underlying material from heat and oxygen, effectively suppressing combustion. Furthermore, the release of ammonia and water vapor dilutes flammable gases.

The advantages of using APP as a flame retardant are numerous. Firstly, it is inherently halogen-free, meaning it does not contribute to the formation of dioxins and furans during a fire, unlike many halogenated counterparts. Secondly, it exhibits low smoke generation and is non-toxic, making it ideal for applications where indoor air quality and occupant safety are paramount. Thirdly, APP offers excellent thermal stability, a crucial factor for processing high-temperature polymers. Its compatibility with various polymer systems, including PVC, polyolefins, epoxy resins, and polyurethanes, makes it a highly versatile additive. For those looking to buy APP, understanding its crystalline phases (Phase I and Phase II) is important, as Phase II generally offers better thermal stability and water insolubility, making it more suitable for demanding applications.
