Product Features
1.Eco-friendly & Safe: No toxic or corrosive gases released during pyrolysis, compliant with RoHS, REACH and other environmental standards.
2.High Whiteness (usually ≥95%), with no negative impact on product coloring.
3.Adjustable Particle Size: We can produce fine powder, micropowder and ultrafine powder ranging from 180 mesh to 12500 mesh (approx. 0.5 μm–88 μm) to suit different processing requirements.

Applications
1.Flame Retardant
It is the most widely used inorganic flame retardant additive, accounting for more than 60% of global aluminum hydroxide consumption.
It absorbs heat and releases water vapor when heated, diluting flammable gases, while forming a protective alumina layer to achieve triple effects: flame retardancy, smoke suppression and anti-dripping.
Widely used in polymer materials such as plastics, rubber, cable compounds, artificial stone, coatings, carpet backing, silicone rubber, PVC, epoxy resin, etc.
2.Filler Function
Used as a filler in artificial marble, artificial boards, SMC/BMC molding compounds, potting materials and acrylic products to improve whiteness, gloss, wear resistance and structural strength.
Used as an abrasive in toothpaste due to its high whiteness, strong cleaning power and good chemical stability.
3.Special Applications
Used in electronic insulation materials (e.g., low-voltage insulation parts, composite insulators) due to low impurity content and excellent insulation performance.
Also applied in papermaking, coatings, catalyst carriers, water purifiers, desiccants, molecular sieves and other fields.
Can be used as raw material for craft products such as glass mosaics and artificial agate.

FAQ
Q: Are you a manufacturer or a trading company?
A: Shandong Leipu New Material Technology Co., Ltd. has 22 years of manufacturing experience, specializing in the production, R&D and sales of white fused alumina, low-sodium white fused alumina, calcined alumina and other series.
We also have an independent trading company – Zibo Zeyang New Material Technology Co., Ltd., providing integrated services for customers with different needs.
Q: What is the maximum filling ratio achievable?
A: With our high bulk density and narrow particle distribution, filling ratios of up to 60–65% by weight can be achieved without compromising processability.
Q: Is the product low in iron content?
A: Absolutely. We strictly control Fe₂O₃ content to be <0.01% (often <0.005%) to prevent yellowing and ensure high electrical insulation properties.
Q: How do you ensure stable quality in mass production?
A: We implement batch control from raw materials, production to finished products, with sample retention and testing for each batch to ensure consistency in composition, particle size, purity and other indicators.
