Description

Melamine Polyphosphate is a halogen-free, nitrogen-phosphorus based flame retardant widely used in polymer engineering. Its primary value lies in its excellent flame-retardant efficiency, low smoke density, and good thermal stability, making it a key component for enhancing fire safety in various materials. This compound is essential for manufacturers in the plastics, coatings, and textiles industries seeking to meet stringent fire safety regulations without using halogenated compounds. The product is supplied as a fine white powder, optimized for easy dispersion and compounding.

Application

• As an intumescent flame retardant in polyolefins such as polypropylene (PP) and polyethylene (PE).
• Flame-retardant additive for engineering plastics including polyamides (PA), polyurethanes (PUR), and epoxy resins.
• Component in fire-resistant coatings, paints, and varnishes for construction materials.
• Use in flame-retardant masterbatches and compounds for wire and cable insulation.
• Application in textiles and non-wovens to impart flame retardancy.
• Synergistic agent in combination with other flame retardants like metal hydroxides to enhance performance.
• Used in the formulation of fire-safe adhesives and sealants.

Quality Control

Our Melamine Polyphosphate is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure consistent performance as a flame retardant, including analysis of phosphorus and nitrogen content, thermal stability, and particle size distribution. A comprehensive Certificate of Analysis (COA) detailing purity, physical properties, and performance indicators is provided with every shipment to guarantee compliance with your technical requirements.

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) and must be kept in its original, sealed packaging until use to prevent moisture absorption, which can affect flowability and performance. Keep away from incompatible materials.
