Description

N,N'-Bis(6-Oxo-6H-Dibenz[C,E][1,2]Oxaphosphorin-6-Ylmethyl)-6-Phenyl-1,3,5-Triazine-2,4-Diamine is a high-performance, halogen-free flame retardant synergist designed for demanding polymer applications. This compound is valued for its ability to significantly enhance the flame retardant efficiency of phosphorus and nitrogen-based systems, particularly in engineering plastics and high-temperature resins. It is primarily sought by formulators and manufacturers in the plastics, electronics, and advanced materials industries who require superior fire safety without compromising on mechanical properties or environmental compliance.

Application

• As a key synergist in halogen-free flame retardant (HFFR) formulations for engineering thermoplastics such as polyamides (PA), polyesters (PBT, PET), and polycarbonates (PC).
• Enhancing the fire resistance of thermoset resins used in printed circuit boards (PCBs), electrical encapsulants, and composite materials.
• Improving the flame retardant performance in wire and cable insulation compounds to meet stringent international safety standards (e.g., UL, IEC).
• Application in high-temperature polymers where thermal stability of the additive is critical.
• Use in specialty coatings and adhesives requiring enhanced fire protection.
• Formulation of fire-safe textiles and fibers through polymer modification.

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 material is moisture-sensitive (hygroscopic); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which may affect performance.
