High Whiteness Aluminum Hydroxide (ATH), also known as alumina trihydrate, is a versatile inorganic environmental-friendly flame retardant and filler. This superfine white powder, characterized by its exceptional whiteness (typically 98-99% grade) and high purity (often exceeding 99.6% Al(OH)³), is manufactured through advanced precipitation reaction technology. Its chemical composition (CAS No. 21645-51-2, Formula: Al(OH)³) and fine particle size (customizable from 1-3μm to 5-100μm) make it an ideal solution for various industrial applications requiring fire safety and material enhancement.
Key Properties & Advantages
This High Whiteness Aluminum Hydroxide powder offers several beneficial properties. It exhibits excellent flame retardancy by decomposing at approximately 205°C, releasing water vapor which absorbs heat, dilutes combustible gases, and forms a protective barrier. As a smoke suppressant, it releases non-corrosive water vapor instead of toxic gases. The product demonstrates good compatibility with polymers, rubbers, and plastics, and can be surface-treated to improve dispersion and loading capacity. Its high whiteness ensures minimal impact on the color of end-products. With low impurities (SiO₂ < 0.02%, Fe₂O³ < 0.08%, Na₂O < 0.3%, Moisture < 0.2%) and oil absorption ranging between 21-35 ml/100g, it contributes to enhanced product quality and performance.
Primary Applications
High Whiteness Aluminum Hydroxide serves as a crucial flame retardant for cable and wire industries, particularly in PVC compounds and silicone rubber formulations. It is widely used in polymer additives for rubber and plastic products like mining conveyor belts, coated cloths, hoses, rubber sheets, carpets, and liners. Its application extends to construction materials such as damping paste, damping boards, and various building products. Furthermore, it functions as a valuable filler in paper production, surface coatings, paints, toothpaste bases, catalyst carriers, water treatment agents, fluoride salts, desiccants, molecular sieves, artificial marble, glass mosaics, and construction material accelerators.
