High Whiteness Aluminum Hydroxide (High Whiteness ATH), chemically represented as Al(OH)₃, is a premium, synthetically precipitated inorganic material distinguished by its exceptional brightness and consistent quality. As a leading supplier with 26 years of experience in the chemical industry, we leverage a mature and stable supply chain alongside refined manufacturing processes to deliver high whiteness aluminum hydroxide that consistently meets the demanding specifications of diverse global markets. Our dedicated team ensures reliable supply and expert technical support.
Defining Characteristics of High Whiteness Aluminum Hydroxide:
1. Superior Whiteness and Brightness: This is the hallmark feature. Our high whiteness aluminum hydroxide undergoes specialized processing to achieve a very high level of brightness (typically >98% measured by standard reflectance methods). This intrinsic whiteness significantly enhances the final color and aesthetic appeal of products it’s incorporated into, reducing the need for expensive whitening agents like titanium dioxide (TiO₂).
2. Excellent Chemical Stability: High whiteness ATH exhibits strong resistance to acids, alkalis, and solvents under typical application conditions. This inertness ensures product integrity and longevity in demanding environments.
3. Effective Flame Retardancy & Smoke Suppression: Like standard ATH, high whiteness aluminum hydroxide decomposes endothermically when exposed to heat (around 200°C), releasing water vapor. This process effectively absorbs heat, dilutes flammable gases, and forms a protective char layer, significantly retarding flame spread and suppressing smoke generation. It serves as a crucial, environmentally friendly, non-halogen flame retardant.
4. Controlled Particle Size Distribution: Our production process allows for precise control over particle size (D50) and distribution. This is critical for optimizing properties like reinforcement, viscosity control in formulations, surface finish, and optical performance in the end product. Fine, controlled particles ensure better dispersion and performance.
5. High Purity: Rigorous purification steps during manufacturing result in a product with minimal levels of impurities like soluble salts, iron oxide (Fe₂O₃), and heavy metals, essential for applications requiring high clarity, electrical properties, or specific chemical resistance.
Key Industrial Applications Leveraging High Whiteness ATH:
1. High-End Plastics & Polymers:
Flame Retardant Filler: Extensively used in epoxy resins, unsaturated polyesters (UP), polyolefins (PP, PE), PVC, rubber (EVA), and wire & cable compounds where stringent flame retardancy (UL 94 V-0 ratings) and low smoke are required, plus superior whiteness is critical for aesthetics (e.g., white appliance parts, bright cables, decorative laminates).
Reinforcing Filler: Contributes to improved mechanical strength, stiffness, and dimensional stability in various polymer systems.
2. Premium Coatings & Paints:
Functional Filler & Extender: Provides excellent matting effects, improves suspension, enhances scrub resistance, and contributes to flame retardancy in high-quality paints, powder coatings, and industrial finishes. Its high whiteness allows for the formulation of brighter, cleaner whites and pastel colors without compromising on performance, often enabling partial TiO₂ replacement for cost optimization.
3. Specialty Paper & Paper Coatings:
Brightness Enhancer & Filler: Used as a filler and coating pigment to significantly improve paper brightness, opacity, smoothness, and printability, especially in high-grade art paper, label stock, and decorative papers where maximum whiteness is paramount.
4. Advanced Synthetic Solid Surfaces:
Primary Filler & Flame Retardant: A major component in engineered stone (quartz composite s) and solid surface materials (e.g., Corian-type). High whiteness ATH provides the essential filler properties, contributes to the material’s structure, and imparts inherent flame retardancy, while its brightness is vital for achieving pure white and vibrant colored slabs.
5. Pharmaceuticals and Cosmetics:
High-Purity Ingredient: Ultra-high purity grades of high whiteness aluminum hydroxide are utilized as an active ingredient in antacids and as a gentle abrasive or opacifying agent in certain toothpaste and cosmetic formulations, benefiting from its chemical inertness and purity.
6. Glass & Ceramics: Used as a source of alumina in some specialty glass formulations and ceramic glazes.
