Products Description
Material processors often face frequent headaches: unstable batch quality of flame‑retardant fillers, inconsistent particle size, excessive moisture causing agglomeration, insufficient whiteness spoiling finished‑product appearance, and failing international environmental regulations. These problems result in defective end‑products, production interruptions and export compliance barriers.
Aluminum hydroxide (Al(OH)₃, short for ATH) is white crystalline inorganic powder, serving as one of the globally mainstream eco‑friendly halogen‑free flame retardants and functional fillers. Our industrial‑grade aluminum hydroxide boasts high purity, superior whiteness, low moisture content and controllable particle‑size distribution. Great batch‑to‑batch consistency is guaranteed, and the product meets REACH and RoHS environmental requirements. It is well‑suited for export‑oriented manufacturing in polymers, composite materials, artificial stone and fine‑chemical sectors, helping you avoid compliance risks and keep stable production quality.
Advantage
Endothermic Heat Absorption
At 200°C, it undergoes endothermic decomposition, releasing 34% water vapor to cool the polymer surface and effectively dilute combustible gases.
Superior Surface Treatment
Optional silane or stearic acid coating enhances compatibility with EVA/PE/PP, significantly improving the tensile strength and impact resistance of composites.
High Dielectric Insulation
Exceptional electrical insulation and arc resistance properties make it an ideal non-conductive filler for high-voltage cable insulation and electronic potting.
Low Oil Demand & Gloss Control
Optimized oil absorption allows for high filler loading while maintaining excellent surface gloss and flowability in premium paper coatings and inks.

FAQ
Q: Can the particle size (mesh) be customized?
A: Yes. We offer various grades, from coarse powder to ultra-fine particles (e.g., 325 mesh, 800 mesh, 1250 mesh, or even sub-micron sizes) to meet different production needs.
Q: What is the difference between industrial and high-whiteness grades?
A: Industrial grade is mostly used for water treatment or basic fillers. High-whiteness grade (over 95%) is specifically required for artificial stone and high-end plastics to ensure a pure, bright finish.
Q: Is it considered a hazardous material for transport?
A: No. Aluminum Hydroxide is classified as non-hazardous and non-toxic. It is safe for international shipping by sea, air, and land.
Q: What is the shelf life of the product?
A: Under proper dry and sealed storage conditions, the shelf life is typically 24 months. Always keep it away from acids and strong alkalis.
Q: Are there any safety precautions for handling?
A: It is a fine powder that can generate dust. We recommend workers wear dust masks, safety goggles, and gloves during handling to avoid respiratory and eye irritation.
