1. 🚒 Flame Retardants
Fireproof coatings, plastics (polyolefins, polyurethanes, epoxy resins, etc.), rubber, cable compounds, fiber textiles (polyester, acrylic, etc.), wood, paper.
Intumescent flame retardancy: Decomposes upon heating to produce non-flammable gases and catalyzes the formation of a dense carbon layer, blocking oxygen and heat. Environmentally Friendly & Low Toxicity: Halogen-free, low smoke emission during combustion, no corrosive gases.

2. 🌱 Agriculture
Liquid compound fertilizers, foliar fertilizers, forest and mountain fire extinguishing agents.
High-Nutrient Formulation: Supplies nitrogen and phosphorus nutrients with near-neutral pH. Enhancement & Stability: Chelates trace elements, prevents phosphorus fixation in soil; undergoes slow hydrolysis in soil for sustained nutrient release.

3. 🍽️ Food Industry
Food emulsifier.
Safety & Stability: Forms or maintains uniform emulsions of oil-water phases in food products, featuring high water-binding capacity and low toxicity.

📝 Key Details & Application Principles

Flame Retardant Mechanism:
It functions as an “acid source” within intumescent flame retardant systems. When materials are heated, it decomposes to produce polyphosphoric acid and ammonia gas. Polyphosphoric acid catalyzes the dehydration and carbonization of carbon-containing substances, forming an expanded, porous carbon foam layer. Simultaneously, non-flammable gases like ammonia cause this layer to expand, effectively isolating external oxygen and heat to achieve flame retardancy.

Material Compatibility:
As an additive flame retardant, it exhibits excellent compatibility with various polymeric materials and is often blended with other flame retardants to enhance effectiveness. Modification techniques like microencapsulation further improve its compatibility with plastics and other materials while boosting flame retardancy efficiency.

Product Classification:
Product properties vary based on polymerization degree (n value). Typically, high-polymerization products (n > 1000) exhibit low water solubility and are primarily used as flame retardants. Conversely, low-polymerization products (n ~ 5-20) demonstrate good water solubility and are mainly employed in fertilizers and food additives.
