Product Overview

Functional Silica Powder is a silica powder designed for targeted filling and reinforcement in different downstream systems. Particle size, surface properties, and functional indicators can be adjusted to improve engineering plastic strength, coating weatherability, adhesive thixotropy, or electrical insulation in electronic materials.

Core Advantages

Adjustable functional type: reinforcement, thickening, insulation, weatherability. Buyers can select a grade matched to the specific performance requirement rather than using a single general-purpose filler across all formulations.

SiO₂ content ≥99.0%, loss on ignition ≤0.15%. In engineering plastics and electronic insulation materials, low LOI reduces volatile release during processing.

Particle size 300–3000 mesh. Covers the fineness range used in functional coatings, engineering plastics, and electronic insulation materials.

Chemical stability. In coating and rubber systems, the filler does not react with the resin system, supporting consistent performance over the product life.

Moisture ≤0.20%. Controlled moisture supports stable handling and dispersion in resin systems.

Application Scenarios

• Engineering plastics
• Functional coatings
• Electronic insulation materials
• Adhesives
• Rubber
• Refractory materials
