Applications
Ammonium Polyphosphate (APP) is widely used in various industries for its versatile properties. It serves as an acid donor in intumescent coatings, making it an essential component in fire protection systems. Additionally, it finds applications in the paper and wood industry, where it enhances the fire resistance of these materials.
In the realm of polyurethane foams, APP acts as a non-halogenated flame retardant, ensuring the safety and compliance of these products. It is also utilized in thermoplastics and polypropylene, providing effective flame retardancy and enhancing the overall performance of these materials.
Moreover, APP is a valuable additive in the production of epoxy resins and unsaturated polyester resins. Its high molecular weight (n>1000) and exceptional stability make it an ideal choice for expanding fire-refractory coatings.
Please note that our APP is manufactured to meet the highest industry standards, ensuring consistent quality and performance.
