As a B2B procurement manager or product formulator in the chemical industry, understanding the nuances of specialty chemicals like Ammonium Polyphosphate (APP) is paramount to ensuring product performance and safety. Ammonium Polyphosphate, identified by CAS number 68333-79-9, is a cornerstone in the development of halogen-free flame retardant systems, widely sought after for its effectiveness in intumescent applications. This article aims to guide you through selecting the right APP grade and understanding its critical role in modern material science.

Ammonium Polyphosphate (APP) functions primarily by undergoing thermal decomposition to release phosphoric acid and ammonia. The phosphoric acid acts as a catalyst, promoting dehydration and charring of the substrate material. This char layer forms an insulating barrier that protects the underlying material from heat and oxygen, thereby inhibiting combustion. This intumescent mechanism is crucial for applications such as intumescent coatings for steel structures, wood, and other combustible materials. When considering purchasing APP, it’s important to note that different phases exist, with Phase II APPs (characterized by a high polymerization degree, n>1000, and a cross-linked structure) offering superior thermal stability and water resistance compared to Phase I APPs.

For manufacturers in China and globally, sourcing high-quality Ammonium Polyphosphate is critical. As a leading supplier of industrial chemicals, we understand the importance of consistent quality and competitive price. Our extensive product portfolio includes various grades of APP, ensuring you can find the perfect fit for your specific formulation needs.
