Key Advantages of Our Aluminum Hydroxide Powder
Fully Customizable Particle Size & Formulation
We offer complete flexibility for particle size customization, with an adjustable D50 range of 0.5-20μm tailored to your exact application needs. This eliminates the need for secondary processing at your facility, streamlines your production workflow, and reduces overall manufacturing costs while ensuring perfect compatibility with your existing formulation.
Ultra-High Purity & Unmatched Batch Consistency
With a minimum Al(OH)₃ purity of 99.5% and strict control over trace impurities, our ATH powder minimizes the risk of product defects in your manufacturing process, preserves exceptional whiteness for high-end products, and delivers stable, repeatable performance across every batch. This consistency is critical for maintaining uniform product quality in large-scale industrial production.
Low Oil Absorption for Superior Processability
Our filler-grade aluminum hydroxide features an optimized low oil absorption rate of 31g/100g, which enhances dispersion in polymer, rubber, and resin matrices. This reduces the consumption of expensive plasticizers and binders in your formulation, lowers raw material costs, and improves the flowability and processability of your mixtures during high-volume production.
Non-Toxic, Eco-Friendly & Globally Compliant
Our ATH powder is a non-halogen, non-toxic, and eco-friendly functional additive, fully compliant with international environmental and safety regulations for industrial manufacturing. It supports your sustainable production goals, helps your end products meet global market compliance requirements, and eliminates the health and environmental risks associated with traditional flame retardant and filler materials.
Industrial Applications
Aluminum Hydroxide Powder for Rubber Manufacturing
As a high-performance additive for rubber formulations, our ATH powder significantly improves the anti-aging, weather resistance, and flame retardant properties of finished rubber products. Its uniform particle size ensures excellent dispersion in rubber compounds, enhancing tensile strength and mechanical performance while reducing reliance on costly specialty additives. It is ideal for automotive rubber components, industrial seals, hoses, and general rubber goods manufacturing.
Aluminum Hydroxide for Premium Papermaking
Our high-whiteness filler-grade aluminum hydroxide is a preferred raw material for high-end papermaking applications. It boosts the opacity, brightness, and printability of paper products, while its consistent particle distribution enhances surface smoothness and sheet strength. It is widely used in the production of decorative paper, cultural paper, specialty packaging paper, and other high-grade paper products.
ATH Powder for Plastics & Polymer Formulations
In plastics and polymer manufacturing, our ATH powder acts as a high-efficiency non-halogen flame retardant and reinforcing filler. It provides excellent smoke suppression and flame retardancy without compromising mechanical properties, and its low oil absorption ensures exceptional compatibility with various polymer resins. It is perfectly suited for engineering plastics, wire and cable insulation, composite materials, and thermoplastic formulations.
Aluminum Hydroxide Powder for Cosmetics & Personal Care
Our ultra-fine, high-purity aluminum hydroxide powder serves as a mild, effective abrasive agent in cosmetic and personal care formulations. With fully customizable particle size, we can tailor the abrasion level to match your product needs, from gentle facial scrubs to toothpaste formulations. Its chemical inertness, non-irritating properties, and strict impurity control ensure full compliance with global cosmetic safety standards.
Beyond these core applications, our R&D team can develop custom ATH solutions for your unique manufacturing needs, including coatings, adhesives, ceramic production, and other specialty industrial sectors.
