NINGBO INNO PHARMCHEM CO.,LTD. is pleased to present information regarding high-performance Aluminum Diethylphosphinate (ADP), a key solution in the field of halogen-free flame retardancy. As industries increasingly move towards safer and more environmentally friendly materials, specialized additives like ADP are becoming indispensable, particularly in sensitive applications such as electronics and high-performance polymers.

Aluminum Diethylphosphinate is a highly effective, non-halogenated flame retardant designed to meet the most rigorous fire safety standards. It is a fine white powder, characterized by its excellent thermal stability, with a decomposition onset typically above 350°C in a nitrogen atmosphere (measured by TGA at 1% weight loss at 10°C/min). This high thermal resistance makes it well-suited for processing in various polymer matrices, including those requiring high processing temperatures.

A critical feature of this Aluminum Diethylphosphinate is its specifically controlled particle size distribution. With a D50 typically less than 3 microns and a D97 less than 10 microns, it ensures superb dispersibility. This superfine nature is particularly advantageous in applications requiring very thin layers or films, such as flexible printed circuits (FPC), flexible copper-clad laminates (FCCL), and thin adhesive layers. Achieving uniform dispersion is key to maximizing flame retardant efficiency and maintaining the mechanical and electrical properties of the base material.

The primary application area for Aluminum Diethylphosphinate is in epoxy resin systems and various thermoplastics. It is highly effective in achieving challenging fire standards, such as UL 94 V-0, often at relatively low addition levels. For instance, in typical epoxy resin formulations, a loading of around 12-15% can enable a 1.6mm thick sample to pass the UL 94 V-0 test. The high phosphorus content, typically 23-24% by weight, contributes significantly to its efficacy as a condensed-phase flame retardant, promoting char formation that protects the underlying material from burning.

Beyond FCCL and FPC, Aluminum Diethylphosphinate finds use in a range of electronic applications including electronic potting compounds, functional adhesives, encapsulants, and rigid copper-clad laminates (CCL). Its inherent electrical properties are favorable, minimizing negative impacts on dielectric constant and dissipation factor, which is crucial for high-frequency electronic circuits. It can also be used in fuel-retardant inks and other specialized coatings.

The benefits of choosing Aluminum Diethylphosphinate are numerous. As a halogen-free solution, it aligns with environmental directives such as RoHS and WEEE, reducing concerns related to potentially toxic combustion by-products associated with halogenated flame retardants. Its high efficiency means lower loading is often required compared to some other non-halogenated alternatives, which helps preserve the mechanical strength and processability of the polymer system. Furthermore, ADP can be used effectively on its own or in synergy with other non-halogenated additives and inorganic fillers to optimize performance for specific formulations and applications.

Proper dispersion is vital when incorporating Aluminum Diethylphosphinate into polymer systems, especially viscous resins like epoxy. Utilizing high-shear mixing equipment, such as high-speed stirrers or bead mills (sand mills), is recommended to achieve optimal dispersion and unlock the full flame retardant potential and avoid agglomeration.

The packaging of Aluminum Diethylphosphinate typically involves robust bags to protect the product during transit and storage. Common packaging sizes include 20kg or 25kg paper bags, suitable for industrial handling. For larger shipments, the material can be palletized, allowing for efficient container loading, such as 10 metric tons per pallet or larger quantities up to 12 or 24 metric tons in 20' and 40' containers, respectively. Maintaining the product in a dry, cool environment is essential to ensure its shelf life, which is generally around 12 months from the date of manufacture when stored correctly.
