Product Description


High-white aluminum hydroxide filler is a high-purity bauxite-derived product, typically appearing as a white or near-white powder, with excellent chemical stability and physical properties.

 


It is produced through the refining and hydrolysis of high-quality bauxite and is widely used as a filler material in plastics, rubber, coatings, paper, and other industrial products to enhance the physical performance and appearance of the final products.


Application Area


Application



1. Plastic and Rubber Industry


Application: Used as a filler, high-white filler improves the mechanical properties, hardness, compressive strength, and UV resistance of plastics and rubbers. It is commonly used in plastics and rubber products in the automotive, construction, and household appliance industries


Advantage: Improves material properties and reduces costs.



2. Electronics Industry

 

Application: Used as an electrical insulation material, high-white filler is applied to the coatings and insulating layers of electrical devices, providing excellent insulation performance. It is commonly used as a filler for PVC wires and cables.

 

Advantage: Enhances the high-temperature resistance, insulation, and long-term stability of electronic products.

Advantage: High whiteness, enhances the gloss and coverage of the coating.

 


5. Construction Industry

 

Application: As a filler for construction paints, wall decoration materials, and other building materials, high-white filler increases the whiteness, smoothness, and durability of the materials.

Advantage: Improves the appearance quality and durability of construction materials, making it ideal for both interior and exterior wall decoration.



6. Other Industry Applications


Paper Industry: Used to increase the gloss and whiteness of paper.

Cosmetics Industry: Used as a component in certain cosmetic products.


Product Advantages


Product Features:

 

l  High Whiteness: High-white aluminum hydroxide filler has an extremely high whiteness, effectively improving the appearance quality of the final product.


      It is especially widely applied in fields that require high whiteness and transparency.

 

l  Good Dispersibility: This filler has excellent dispersibility, allowing it to blend uniformly with various substrates without easily precipitating.

 

l  High Purity: The purity of this material is high, typically above 99%, making it suitable for industries that require high purity materials.

 

l  Chemical Stability: It has strong chemical stability, is resistant to acid and alkali corrosion, and can adapt to various environmental conditions, ensuring long-term stability under complex conditions.

 

l  Low Viscosity: When applied, high-white aluminum hydroxide filler can reduce the viscosity of the product, improving processing efficiency.
