Understanding High Whiteness Aluminum Hydroxide (CAS 21645-51-2)
High Whiteness Aluminum Hydroxide, primarily composed of Al(OH)3, is a fine white crystalline powder. It is recognized for its non-toxic, odorless nature, and low environmental impact. This versatile material offers excellent flow properties and superior whiteness, achieved through stringent control of alkali and iron content during production.
Key Properties and Advantages:
1. Effective Fire Safety: This aluminum hydroxide compound acts as a highly efficient flame retardant filler and smoke suppressant. It functions primarily through endothermic decomposition, absorbing significant heat when exposed to fire, releasing water vapor (approximately 34.6% of its mass as water upon decomposition around 180-200°C). This process effectively cools the material, dilutes flammable gases, and forms a protective char layer. Crucially, it minimizes smoke generation, prevents dripping of molten material, and avoids releasing toxic gases during combustion, enhancing safety in fire scenarios.
2. Exceptional Whiteness & Purity: Our High Whiteness Aluminum Hydroxide grade is distinguished by its superior brightness. Rigorous manufacturing controls ensure minimal impurities, particularly low alkali and iron levels, contributing to its pristine white appearance. This high whiteness is critical for applications where color consistency and aesthetics are paramount, such as in premium polymer compounds, coatings, and adhesives.
3. Surface Modification (Activated Grades): Utilizing advanced domestic production techniques, we offer activated High Whiteness Aluminum Hydroxide. This involves surface treatment with carefully selected coupling agents and processing aids. The activation process significantly enhances compatibility with various polymer matrices (like PVC, PE, PP, EVA, rubber, and unsaturated polyesters). Benefits include:
Improved Dispersion: Treated particles integrate more uniformly within host materials.
Enhanced Mechanical Properties: Better interfacial adhesion often leads to improved tensile strength and impact resistance in the final composite.
Optimized Rheology: Contributes to smoother processing and flow characteristics.
Higher Filler Loading: Allows for increased incorporation levels without sacrificing key properties, improving cost-efficiency.
4. Consistent Particle Characteristics: We provide grades featuring controlled particle size distribution and fine particle size. A narrow distribution ensures predictable performance and uniformity in end products. Low bulk density is another advantageous feature, particularly relevant for specific compounding processes.
5. Versatility and Reactivity: As an amphoteric compound, High Whiteness Aluminum Hydroxide reacts with both strong acids and strong bases. Its thermal decomposition pathway (Al(OH)3 → Al2O3 + 3H2O) is fundamental to its flame retardancy mechanism and is also exploited in other industrial processes like ceramic production.
