What is Ammonium Polyphosphate(APP)?
Ammonium polyphosphate (APP) is a high-performance, eco-friendly inorganic polymer widely adopted across industrial fire safety and agriculture sectors. Featuring excellent thermal stability, non-toxicity and halogen-free properties, this multi-functional chemical has seen surging global market demand amid rising global environmental and safety standards.
APP is mainly divided into Phase I and Phase II. Heat-resistant APP Phase II dominates the market, suitable for various high-temperature industrial scenarios. Agriculture is its largest application field, where water-soluble APP acts as an efficient nitrogen-phosphorus composite fertilizer. It greatly improves soil nutrient activity and crop absorption efficiency, significantly reducing fertilizer waste and soil pollution compared with traditional fertilizers, supporting sustainable and precision agriculture development.
As a top-tier halogen-free flame retardant, APP holds vital industrial value. It forms a protective char layer under high temperature to isolate heat and oxygen, effectively curbing flame spread. It is widely used in building materials, cables and new energy vehicles, solving thermal runaway risks for EV batteries.
Driven by strict fire safety regulations, green agriculture, and booming new energy industries, the global APP market grows steadily. Industry insiders predict continuous market expansion through 2034, with upgraded high-purity APP products unlocking broader industrial application potential.
