Description

Fused silica is of high purity, low ionic impurities, superior electrical insulation properties, low linear coefficient of thermal expansion and stable particle size distribution. They are most ideal as filllers for epoxy molding compound used in electronic industry and coating material, paints ceramics, metal casting and refractories.
