Silica
Silica is primarily used to enhance the mechanical properties of silicone rubber, plastics, paints, and coatings, such as improving abrasion resistance and strength. Additionally, silica powder possesses excellent insulation and thermal stability, making it widely applicable in industries such as electronics, cables, and semiconductor manufacturing. Silica products are categorized into two types based on the manufacturing process and crystalline structure: Fine Ground Silica, Fumed Silica and Precipitated Silica.
Fine Ground Silica
Product Features:
- High purity level of 98% fillers, with average micron topsize of 5µ, 10µ, and 30µ
- Low water content, good ductility and whiteness
- Suitable for additives of paints, adhesives, silicone rubbers, and epoxy resins

Fumed Silica
Product Features:
- Fluffy, white, and amorphous loose powder
- High specific surface area, high purity, and unique surface chemistry make it be used widely in various industrial applications
- Average particle size is from 7 to 40 nm, and ranges from 50 to 300 ㎡/g in specific surface area with BET
