Easy-Dispersion ATH

The easily-dispersible ATH (Aluminum Trihydroxide) flame retardant is a high-performance inorganic halogen-free flame retardant material developed through a three-in-one process of "precise surface energy control + composite modification + morphology optimization." It addresses industry pain points such as severe agglomeration, uneven dispersion, and soaring processing viscosity caused by the high polarity and surface energy of traditional ATH. With increasing penetration rates in sectors like wires and cables, coatings, rubber and plastic products, and new energy auxiliary materials, it is particularly suitable for processing scenarios with stringent dispersion requirements, such as high-speed mixing, film extrusion, and precision injection molding.

Core strengths

1. Anti aggregation crystal control technology, achieving breakthroughs in dispersion at normal temperatures

-Dispersion can be achieved by stirring at room temperature: The surface of the powder is treated with special charge balance, and the repulsive force between particles is greater than the attractive force. Heavy equipment such as high-speed dispersers and sand mills are not required. Micro scale uniform dispersion can be achieved by stirring at room temperature and low speed (300-500r/min), and the dispersion time is shortened by more than 60%;

-Zero aggregation high uniformity: The dispersion uniformity is stable at ≥ 99%, the particle size distribution SPAN is ≤ 1.3, there are no large particle aggregates, and after addition, the surface of the product has no pockmarks, pinholes, or weak mechanical properties. The quality consistency is improved to over 99.5%;

-Anti secondary flocculation characteristics: The slow-release dispersant coated on the surface can slowly migrate in the substrate, maintaining the particle dispersion state continuously. Even after undergoing processing steps such as high-temperature extrusion and high-pressure molding, there will be no problems such as powder agglomeration or settling, ensuring the long-term stability of product performance.

2. Targeted interface modification technology, balancing high compatibility and low performance degradation

-Multi substrate seamless adaptation: Customizable interface modification solutions for rubber, coating, adhesive, and other types can be used to adapt to substrates such as EVA, PVC, epoxy resin, polyurethane, etc., forming a dual combination of "physical winding+chemical anchoring" with the molecular chain of the substrate, increasing the interface bonding strength by more than 50%;

-Excellent performance under high filling: under 55% high filling content in EVA cable material system, the tensile strength can reach 18.2MPa, the elongation at break ≥ 420%, the retention rate of mechanical properties ≥ 95%, which is 35% higher than that of conventional ATH, while maintaining the excellent flexibility and anti-aging performance of the product;

-Low oil absorption value reduces costs and increases efficiency: The oil absorption value is as low as 12-15mL/100g, which is 40% lower than conventional ATH. It can significantly reduce the amount of resin and plasticizer used in the substrate system, reduce raw material costs by 25% -30%, improve melt flowability, and reduce equipment wear during processing.3. Spherical shape optimization: reduce dispersion resistance

The process of "seed induced nucleation+spray granulation" is adopted to customize and develop spherical and easy to disperse ATH, which is different from traditional irregular particles:

-Excellent flowability: sphericity ≥ 0.92, packing density increased by 35%, sliding resistance between particles reduced by 50% during mixing and extrusion processes, dispersion efficiency increased by 2 times, suitable for automated continuous production lines;

-Reduced processing wear: Spherical particles reduce the wear rate of equipment screws and molds by 70%, prolong equipment service life, and reduce production costs;

-Flame retardant efficiency improvement: Spherical particles form a uniform "flame retardant network" in the substrate, increasing thermal conductivity efficiency by 25%. Adding 35% can achieve UL94 V-0 level, reducing the filling amount by 20% compared to traditional ATH.

4. Narrow particle size distribution design: constructing a dense dispersion system

Adopting the technology of "multi-stage airflow crushing+AI intelligent classification" to achieve precise particle size control and narrow distribution design:

-Particle size customization: covering the entire range of 0.5-10μm, D50 can be accurately controlled within 1-5μm, Span value ≤ 0.8 (industry average ≥ 1.2), D90/D10≤2.5， Avoid agglomeration of large particles and secondary aggregation of small particles;

-Dense filling: By synergistically stacking coarse and fine particles, the filling density is increased by 30% while ensuring high dispersibility, making the mechanical properties of the composite material more uniform and improving the surface smoothness by 1 level;

-Testing guarantee: Dual testing with laser particle size analyzer and scanning electron microscope (SEM) is adopted. Each batch of products is provided with a particle size distribution report and microscopic dispersion morphology diagram to ensure stable dispersion performance.
