Description

Melamine Polyphosphate is a halogen-free, nitrogen-phosphorus based flame retardant widely recognized for its excellent thermal stability and low smoke emission. This compound is crucial for enhancing the fire safety of polymer materials without compromising their mechanical properties or environmental profile. It is an essential additive for manufacturers in the plastics, coatings, and electronics industries seeking to meet stringent global fire safety regulations.

Application

• Flame Retardant for Engineering Plastics: Key component in polyamides (PA6, PA66), polyesters (PBT, PET), and polyurethanes for automotive, electrical, and electronic components.
• Fire-Safe Polymer Compounds: Used in intumescent coatings, cable jacketing, and construction materials to provide char-forming, flame-inhibiting properties.
• Synergistic Flame Retardant Systems: Often combined with other agents like metal hydroxides or expandable graphite to enhance overall fire performance and reduce loading levels.
• Thermoplastic Elastomers (TPEs) and Adhesives: Imparts flame retardancy to flexible materials used in wire & cable, seals, and industrial adhesives.
• Textile Back-Coating: Applied to fabrics for upholstery, curtains, and protective clothing to improve fire resistance.

Quality Control

Our Melamine Polyphosphate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance as a flame retardant, including assessments of phosphorus/nitrogen content, thermal stability (TGA), and particle size distribution. A Certificate of Analysis (COA) documenting key specifications is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the original container tightly sealed to prevent moisture absorption, which can affect flowability and performance.
