Product Description

Product Overview

This product is manufactured from high-purity quartz sand through high-temperature fusion, ultra-fine grinding, and hydrophobic surface modification. It features high purity (≥99%), low moisture absorption, excellent dispersibility, and chemical stability. Widely used in high-end coatings, electronic packaging, silicone rubber, adhesives, and other fields, it significantly enhances material weather resistance, mechanical strength, and dielectric properties.


Key Parameters

Parameter Specification/Description
Purity ≥99%
Particle Size (D50) 0.5μm-50μm (custom grading available)
Hydrophobic Angle ≥120° (water contact angle)
Whiteness ≥92%
Moisture Content ≤0.5%
pH Value 6.0-7.5 (neutral stability)


Product Advantages


  • Ultra-High Purity: Extremely low impurity content (≤1%), ensuring safety in sensitive applications such as electronics and optics.

  • Strong Hydrophobicity: Specially treated surface significantly reduces moisture absorption, prevents caking, and improves compatibility with organic materials.

  • Controllable Particle Size: Customizable grading within the 0.5μm-50μm range to meet diverse filling requirements.

  • Excellent Thermal Stability: High-temperature resistance (≥1600°C), suitable for high-temperature processing environments.


Applications


  • Electronic Materials: IC packaging, epoxy resin potting compounds, high-frequency substrate filling, reducing dielectric loss.

  • Silicone Rubber: Reinforcing filler, improving tear resistance and aging performance.

  • High-End Coatings: Enhancing wear and corrosion resistance, reducing coating cracking.

  • Adhesives: Optimizing rheological properties and increasing bonding strength.


Technical Support & Services


  • Particle size distribution analysis (laser particle size analyzer report) and MSDS available.

  • Sample trials and customized surface treatments (e.g., varying hydrophobic grades) supported.

  • Packaging: 25kg/bag, or customized packaging upon request.
