Silica Fine Powder

Silica Fine Powder is a general-purpose fine silica powder for buyers who balance fineness, purity, and cost. It is used as a filler in coatings, plastics, rubber, and building material systems. The product is positioned for routine production rather than high-end fine filler applications.

Particle size range 325–2500 mesh. This covers the common fineness band for general coatings, plastic filling, and rubber compounding, so buyers can select one grade across multiple product lines.

SiO₂ content ≥99.0%, loss on ignition ≤0.15%. In rubber and plastic systems, lower LOI reduces volatile release during processing and limits void formation in the finished part.

Whiteness ≥90. Suitable for neutral and light-colored building coatings and plastic products where a high whiteness level is not the primary requirement.

Batch testing before packaging. Each batch is checked in the laboratory and released only after it passes. For buyers running continuous lines, this reduces incoming inspection workload.

Moisture ≤0.30%. Controlled within a range that supports stable storage and handling in general filler applications.
