Key Advantages of Our Narrow-Distribution Aluminum Hydroxide Filler
High-Efficiency Flame Retardancy with Low Smoke Emission
Our UL94 V-0 compliant aluminum hydroxide powder delivers exceptional fire suppression performance, effectively inhibiting flame spread in polymer and building material systems. Unlike halogenated flame retardants, it produces minimal smoke and toxic fumes during combustion, aligning with global low-toxicity fire safety regulations for public and industrial spaces.
Ultra-Uniform Narrow Particle Size Distribution
The tight, narrow particle size grading ensures consistent dispersion in base materials, eliminating agglomeration and uneven performance that plagues broad-distribution fillers. This uniformity translates to stable processing performance, consistent mechanical properties, and predictable flame retardant efficacy across every production batch.
High Purity & Stable Chemical Performance
With a minimum Al(OH)3 purity of 99.6% and ultra-low impurity levels, this high-purity aluminum hydroxide flame retardant filler maintains exceptional chemical stability under normal processing and service conditions. Its neutral pH value (7) prevents corrosion of processing equipment and avoids adverse reactions with other additives in your formulation.
Global Regulatory Compliance
Our filler meets strict international safety and environmental standards, with full ISO 9001 quality management system certification for production. It complies with major global flame retardant and material safety regulations, making it suitable for export-oriented manufacturing and multinational supply chains.
Industrial Applications
Wire & Cable Manufacturing
As the leading aluminum hydroxide filler for flame retardant cables, it enhances both insulation performance and fire resistance of cable sheathing and insulation layers, ideal for power cables, communication cables, and industrial wiring systems.
Polymer & Plastic Formulation
Widely used in PP, PE, PVC and other thermoplastic and thermoset polymers, it provides reliable flame retardancy for injection molded parts, extruded profiles, and plastic components used in automotive, electronics, and consumer goods.
Fire-Resistant Building Materials
It is a core additive for fireproof coatings, gypsum boards, and other construction materials, improving fire resistance ratings of interior and exterior building elements for commercial, residential, and industrial construction projects.
FAQ
What particle size ranges are available for your narrow-distribution aluminum hydroxide filler?
We offer a strictly controlled D50 particle size range of 0.5-20μm with narrow distribution, and we can customize specific particle size specifications to match your unique formulation and processing requirements.
Does this filler meet international flame retardant standards?
Yes, our narrow-distribution aluminum hydroxide filler is fully compliant with UL94 V-0 flame rating standards, and our production process is certified under ISO 9001 and ISO 14001 management systems, meeting global industrial safety requirements.
