Introduction
Shandong Crownchem Industries Co., Ltd., established in 2013 and rooted in over two decades of expertise from its predecessor Zibo Xinye Chemical Co., Ltd., is a globally recognized supplier of specialty chemicals. Our flagship product, Aluminum Hydroxide (Al(OH)3), CAS 21645-51-2, stands out as a premium flame retardant and functional filler trusted by industries worldwide. With ISO-certified production facilities and a commitment to innovation, we deliver high-performance solutions tailored to meet diverse industrial needs.
Product Overview
Aluminum Hydroxide, a white crystalline powder, is a versatile, eco-friendly compound renowned for its non-toxic, odorless, and pollution-free properties. As a leading aluminum hydroxide manufacturer, we produce grades with exceptional purity (>99.5%), low alkali/iron content, and superior whiteness, ensuring compatibility with polymers, coatings, cables, and construction materials. Its unique dual functionality as a flame retardant and smoke suppressant makes it indispensable for fire safety applications.
Key Features & Advantages
1. Advanced Flame Retardancy
- Acts as an eco-friendly flame retardant by releasing water vapor at 180–220°C, cooling surfaces, diluting flammable gases, and suppressing smoke.
- Eliminates toxic emissions and dripping during combustion, enhancing safety in plastics, rubber, and electrical insulation.
2. Surface-Modified & High Performance
- Activated aluminum hydroxide undergoes advanced surface treatment with coupling agents for improved dispersion, adhesion, and mechanical strength in composites.
- Narrow particle distribution (D50: 1–20 µm customizable) ensures optimal filler loading without compromising product aesthetics or processability.
3. Multi-Industry Compatibility
- Ideal for PVC, EVA, epoxy resins, silicone rubber, and wire & cable compounds.
- Enhances thermal stability, arc resistance, and tracking resistance in electrical applications.
4. Cost-Effective & Sustainable
- Reduces raw material costs by replacing partial resin content while maintaining performance.
- Compliant with RoHS, REACH, and UL94 standards, supporting green manufacturing initiatives.
