Description

Zinc Diethylphosphinate is an organophosphorus metal salt with the CAS number 284685-45-6, valued for its role as an effective flame retardant and smoke suppressant in polymer systems. This compound matters because it provides a halogen-free, environmentally friendly solution for enhancing the fire safety of materials while maintaining good thermal stability and mechanical properties. It is primarily needed by manufacturers in the plastics, textiles, and coatings industries seeking to meet stringent fire safety regulations without compromising material performance.

Application

• Primary flame retardant for engineering plastics such as polyamides (PA), polyesters (PBT, PET), and polyurethanes (PU).
• Smoke suppression additive in wire and cable insulation compounds.
• Synergistic component in intumescent fire-retardant coatings and paints.
• Flame retardant filler for synthetic fibers and textiles.
• Additive for epoxy resin systems in electronic encapsulants and circuit boards.
• Component in flame-retardant masterbatches for compounding with various polymers.
• Research and development of novel, halogen-free fire safety materials.

Quality Control

Our Zinc Diethylphosphinate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance as a flame retardant. Key parameters such as active content, zinc content, moisture level, and particle size distribution are controlled. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee product integrity and traceability.

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). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture. Separate from strong oxidizing agents.
