Description

Tri[1,3,5-Triazine-2,4,6-Triamine] Diphosphate is a high-performance, nitrogen-phosphorus based flame retardant additive. This compound is engineered to provide superior fire resistance and thermal stability to polymer matrices while maintaining excellent processing characteristics. It is a critical material for manufacturers in the plastics, electronics, and construction industries seeking to meet stringent international safety and environmental regulations. Its specific properties make it an ideal choice for engineering thermoplastics and thermoset resins.

Application

• Primary flame retardant for engineering thermoplastics such as polyamides (nylon), polyesters (PBT, PET), and polyolefins.
• Key additive in thermoset resins for printed circuit boards (PCBs) and electronic encapsulants to achieve UL 94 V-0 ratings.
• Enhances fire safety in construction materials, including wire and cable insulation, and protective coatings.
• Used in the formulation of fire-resistant textiles and foams for automotive and aerospace interiors.
• Component in intumescent coating systems that expand to form an insulating char layer when exposed to fire.
• Applicable in specialty adhesives and sealants requiring improved flame retardancy.

Quality Control

Our Tri[1,3,5-Triazine-2,4,6-Triamine] Diphosphate is manufactured under a strict quality management system. Every batch is tested to ensure it meets precise specifications for purity, thermal stability, and particle size distribution, which are critical for consistent performance in flame retardant applications. Certificates of Analysis (COA) documenting key parameters are provided with each shipment to guarantee supply reliability and product consistency.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
