Aluminum Diethyl Phosphinate
AP1050A ( OP930)
CAS:225789-38-8
Product Description: It is a halogen-free flame retardant based on organic phosphinates. The full name is Aluminum Diethyl Phosphinate. This flame retardant is a kind of white powder or masterbatch, an organic phosphonic acid salt. It is not hydrolyzed, not precipitated, has good self-extinguishing properties into carbon.
Application：It is suited as flame retardant for thermoplastics and thermosets. It has high phosphorus content, good thermal stability and excellent flame retardant efficiency. As a flame retardant, it can be used separately, also can be used together with other flame retardants. Both two different applications have good effects.

Product Introduction: Aluminum Diethyl Phosphinate (ADP)
Aluminum diethyl phosphinate (ADP), also known as Aluminum Diethylphosphinate , is a halogen-free flame retardant widely used in engineering plastics and thermoset resins. Below is a detailed overview of its properties, applications, and benefits, synthesized from authoritative sources.
ADP is an organic phosphinate-based compound (CAS No. 225789-38-8) with the chemical formula C12H30AlO6P3. It appears as a white powder or granule and is characterized by high thermal stability and environmental safety. Its non-hygroscopic nature and insolubility in water and common solvents (e.g., acetone, toluene) make it suitable for high-temperature polymer processing.
Phosphorus Content: 23–24% (w/w), ensuring high flame-retardant efficiency.
Thermal Stability: Decomposes above 350°C (TGA 1% weight loss), compatible with processing temperatures up to 350°C.
Physical Characteristics:
Bulk Density: 250–600 kg/m³ (varies by product form).
Particle Size (D50): 8–40 µm (adjustable for specific applications).
Moisture Content: ≤0.5%.
Certifications: Achieves UL 94 V-0 flame retardancy at thicknesses as low as 0.4 mm.
ADP is primarily used in halogen-free flame-retardant formulations for:
Polyamides (PA6, PA66): Effective in both glass-fiber-reinforced and unreinforced grades, enhancing flame resistance while maintaining mechanical and electrical properties .
Polybutylene Terephthalate (PBT): Recommended for high-temperature applications due to its thermal stability.
Thermosets and Polyesters: Suitable for epoxy resins and PET, often as a replacement for Clariant’s OP series (e.g., OP930, OP1312)
Environmental Safety: Halogen-free, with low toxicity and minimal environmental impact.
Performance:
Prevents dripping during combustion (anti-dripping effect).
Maintains polymer colorability and electrical properties.
Suitable for lead-free soldering processes.
Versatility: Available in powder or masterbatch forms, tailored for specific processing needs (e.g., finer particles for TPE or PU).
Drying: Predrying the polymer is recommended, but ADP itself typically does not require drying unless extreme moisture sensitivity is a concern (e.g., 4 hours at 120°C) .
Dispersion: Requires homogeneous mixing during polymer processing to ensure optimal flame retardancy.
Storage: Store in dry, room-temperature conditions; packaged in 25 kg paper bags with PE liners .
ADP is positioned as a cost-effective alternative to Clariant’s OP series, with comparable performance in nylon and polyester applications.
Conclusion
Aluminum diethyl phosphinate stands out as a high-performance, eco-friendly flame retardant for demanding applications in electronics, automotive, and aerospace industries. Its combination of thermal stability, regulatory compliance, and versatility makes it a preferred choice for modern halogen-free formulations.
