In the context of global environmental regulations tightening and the industry’s increasing focus on safety, halogen-free flame retardants have become a core demand in fields such as plastics, coatings, and textiles. Among them, Ammonium Polyphosphate (APP) stands out as a high-performance, eco-friendly solution, winning wide recognition for its excellent flame-retardant efficiency and low environmental impact. As a professional manufacturer with 18 years of experience in halogen-free flame retardants, we are committed to providing high-quality APP products and customized solutions for global clients.
Ammonium Polyphosphate is a non-toxic, halogen-free inorganic flame retardant. It is composed of phosphate groups and ammonium ions, with its performance largely determined by polymerization degree, a key indicator that directly affects flame-retardant durability, water resistance, and compatibility with base materials.
APP is white crystalline powder or granular solid, with good dispersibility in base materials (e.g., plastics, resins).It has excellent heat resistance, with decomposition temperature above 250℃. It remains stable during high-temperature processing of polymers, avoiding decomposition-induced defects.100% halogen-free, low smoke, and non-toxic.
Leveraging its excellent performance, our APP products are widely used in multiple industries, providing reliable flame-retardant protection for end products:
Plastics Industry: Used in flame-retardant modification of polypropylene (PP), polyethylene (PE), and ethylene-vinyl acetate (EVA) — common in electrical appliances (e.g., wire and cable insulation), automotive parts (e.g., interior panels), and building materials (e.g., plastic pipes).
Coatings & Adhesives: Added to intumescent fire-retardant coatings for steel structures, wood, and concrete buildings; also used in flame-retardant adhesives for electronics and furniture.
Textiles & Paper: Applied in flame-retardant finishing of fabrics (e.g., curtains, upholstery) and paper products (e.g., packaging materials for electronics), meeting fire safety standards for public places.
Construction Materials: Mixed into cement, mortar, and foam concrete to enhance the fire resistance of building components, such as fire doors and partition walls.
With 18 years of focus on halogen-free flame retardants, we have established a complete production and R&D system, bringing unique advantages to global clients.
We own an independent R&D team and laboratory, dedicated to optimizing APP performance. We also customize products based on client needs, such as adjusting particle size, polymerization degree, and surface treatment to match specific application scenarios. Beyond standard APP, we offer a range of specialized products to meet diverse demands:
Crystalline Type II APP, Melamine Polyphosphate etc. We adopt fully automated production lines to ensure consistent product quality and high output. From raw material selectionto final packaging, each step is monitored by professional quality inspectors. Our products undergo rigorous testing before shipment, with a qualification rate of 100%. Our APP products are exported to Europe, North America, Southeast Asia, and other regions, winning high praise for our product quality and after-sales service.
Whether you are looking for standard APP products, high-polymerization customized solutions, or technical support for flame-retardant applications, we have the expertise and experience to meet your needs. With 18 years of dedication to halogen-free flame retardants, we are committed to becoming your reliable long-term partner in the global market.
