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.

Industry Applications

1. Flame Retardant Solutions

• Plastics & Polymers: PVC, polyolefins, epoxy, and polyurethane systems.

• Wire & Cable Coatings: Complies with low-smoke, zero-halogen (LSZH) standards.

• Automotive & EV Batteries: Battery casings and components requiring UL 94 V0 ratings .

• Construction Materials: Insulation, cladding, and composite panels.

2. Functional Filler

• Solid Surfaces & Artificial Marble: Provides strength, whiteness, and texture consistency .

• Paints, Coatings, & Adhesives: Improves opacity, weather resistance, and filler loading.

• Rubber & Sealants: Enhances mechanical properties and flame resistance.

• SMC/BMC Composites: Reduces shrinkage and improves mold flow.

3. Chemical Intermediate

• Raw Material for producing Aluminum Sulfate and Polyaluminum Chloride (PAC) used in water treatment .

• Catalyst Carrier & Adsorbent in specialized chemical processes.

Market Outlook & Regulatory Compliance

The global alumina trihydrate market is projected to reach USD 2.94 billion by 2030, growing at a CAGR of 6.60% . This growth is driven by:

• Stringent Fire Safety Regulations in Europe and North America (e.g., CPR, UL 94).

• Rising Demand for Eco-Friendly Flame Retardants – ATH is non-toxic and halogen-free.

• Expansion in Construction, Automotive, and Electronics Sectors.

Our Chalco ATH meets international standards, including ISO 9001, and is tested for flame retardancy (e.g., IEC 60707), ensuring compliance for global exports.
