Product Description

YUEJIANG Brand - Precision-Grade Precipitated Silica (600-mesh)

YUEJIANG Brand Precision-Grade Precipitated Silica is expertly produced using high-quality precipitated silica, refined to achieve an ultra-fine particle size of 600-mesh. This silica closely mimics the properties of fumed silica, benefiting from advanced processing techniques that ensure a very narrow particle size distribution.

Key Features:

• High Purity: With SiO2 content exceeding 98%, it provides exceptional consistency and quality.
• Superior Performance: Features a high BET surface area (230 - 250 m²/g) and a low D50 (≤6.0 μm), resulting in outstanding reinforcing properties and dispersion.
• Versatile Applications: Ideal for use in silicone rubber, high-temperature adhesives, paints, inks, tires, shoe soles, coatings, cosmetics, pesticides, textiles, and toothpaste.
