Key Advantages of Our Ammonium Polyphosphate
Superior Halogen-Free Flame Retardancy
Our Ammonium Polyphosphate (APP) provides excellent flame retardant properties without relying on halogens, contributing to a safer and more environmentally friendly product profile. It is an ideal choice for applications demanding low smoke and non-toxic emissions when materials ignite.
Versatile Application in Intumescent Systems
APP is a cornerstone in intumescent flame retardant systems. When heated, it decomposes to form phosphoric acid, which promotes char formation and acts as a barrier, effectively insulating the underlying material from heat and oxygen. This makes it ideal for coatings, wood, textiles, and plastics.
High P-N Content for Synergistic Effects
With a high phosphorus and nitrogen content, our Ammonium Polyphosphate exhibits a synergistic effect that significantly boosts flame retardancy. This chemical synergy allows for greater efficiency and cost-effectiveness in formulations, meeting stringent fire safety requirements.
Diverse Applications for Ammonium Polyphosphate
Coatings and Paints
Utilize our APP as a critical additive in intumescent coatings and paints to provide excellent fire protection for structural steel, wood, and other substrates, meeting demanding fire resistance standards.
Plastics and Polymers
Incorporate our Ammonium Polyphosphate into polyolefins, polyurethane, epoxy resins, and other polymers to enhance their flame retardancy, crucial for electronics, construction, and automotive applications.
Textiles and Fibers
Our APP is an effective flame retardant for textiles and fibers, offering durable fire resistance for applications ranging from upholstery to industrial fabrics, ensuring enhanced safety.
Wood and Paper Treatment
Apply our Ammonium Polyphosphate for the flameproof treatment of wood and paper products, providing essential fire safety for construction materials, furniture, and decorative items.
