Description

Melamine Pyrophosphate is a halogen-free, nitrogen-phosphorus based flame retardant widely used in polymer formulations. Its primary value lies in its ability to impart excellent flame retardancy while minimizing smoke and toxic gas emission during combustion. This compound is essential for manufacturers in the plastics, coatings, and textiles industries seeking to meet stringent fire safety regulations without compromising on environmental or health standards. Melamine Pyrophosphate CAS NO 15541-60-3 offers a synergistic balance of phosphorus and nitrogen for efficient condensed-phase flame retardant action.

Application

• As an intumescent flame retardant in polyolefins such as polypropylene (PP) and polyethylene (PE).
• Flame retardant additive for engineering plastics including polyamides (nylon) and thermoplastic polyurethanes (TPU).
• Component in fire-resistant coatings and paints for construction materials and electrical cables.
• Use in epoxy resin systems for printed circuit boards and electronic encapsulants.
• Flame retardant treatment for textiles, non-wovens, and synthetic fibers.
• Application in rubber compounds to enhance fire safety in automotive and industrial components.
• Synergistic use with other flame retardants like metal hydroxides to improve performance and reduce loading.

Quality Control

Our Melamine Pyrophosphate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent performance as a flame retardant, including assay, phosphorus content, nitrogen content, and particle size distribution. Certificates of Analysis (COA) are provided with each shipment, detailing key parameters. We adhere to relevant industry standards and our production processes are designed to ensure high purity and reliable performance in your formulations.

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 container tightly sealed to prevent absorption of atmospheric moisture, which can affect flow properties and performance. Keep away from incompatible materials such as strong bases.
