Chalco Brand Aluminium Hydroxide (Aluminum Trihydrate) – Premium Flame Retardant & Functional Filler
ZHENGZHOU MAHACO INDUSTRIAL CO., LTD is a trusted global supplier of Chalco brand Aluminium Hydroxide (Aluminum Trihydrate, ATH) – a high-purity, versatile chemical engineered for flame retardancy, filling, and smoke suppression across industries. Sourced directly from Chalco (Aluminum Corporation of China Limited), a leading global producer , our ATH guarantees consistent quality, reliability, and performance for applications ranging from plastics and rubber to construction materials and synthetic surfaces.
What Is Chalco Brand Aluminium Hydroxide (ATH)?
Aluminum Trihydrate (Al(OH)₃, CAS No. 21645-51-2) is an industrial-grade, white crystalline powder derived from bauxite via the Bayer process. It serves as both an effective halogen-free flame retardant and a multi-purpose functional filler. The Chalco brand is synonymous with high purity, controlled particle size distribution, and exceptional whiteness – making it a preferred choice for safety-critical and high-value manufacturing processes worldwide .
Key Product Advantages
1. Exceptional Flame Retardancy & Smoke Suppression
Endothermic Decomposition: Releases water vapor at ~180°C–220°C, absorbing heat and diluting combustible gases.
Non-Toxic & Halogen-Free: Meets international environmental and safety standards (e.g., REACH, UL 94) .
Char Formation: Creates a protective layer that slows flame spread and reduces smoke density.
2. High Purity & Quality Consistency
Purity ≥99.6% with minimal impurities (SiO₂ ≤0.02%, Fe₂O₃ ≤0.008%) .
Controlled Particle Size (D50): 1–100 µm – customizable for specific application needs.
Whiteness ≥92–99% – ideal for aesthetic-sensitive products like solid surfaces and coatings.
3. Multi-Functional Performance
Low Oil Absorption (21–35 ml/100g): Reduces resin demand, saving costs.
Excellent Dispersion & Flowability: Ensures uniform mixing in polymers, rubbers, and liquid systems.
UV Resistance & Anti-Tracking: Enhances durability in outdoor and electrical applications.
