Low adhesion

Heated to 900 ℃ is not melting, 400 ℃ heat was less than 5%

After calcination can get spherical silica particles

Narrow particle size distribution

Application:

Rubber industry: improve the smoothness of the rubber and improve the wear resistance of the rubber

Coatings and printing ink: adjust the glossiness and color chroma, anticaking, improving wear resistance.

Synthetic resin: improve the wear resistance of epoxy resin, acrylic resin, polyester resin and ABS resins. Resistance to agglomerate, improve smoothness, keeping the transparency of PE, PP and other plastic film

Cosmetics: smooth handle agent, filling agent.

The LED industry: used as the light diffusion agent, it has excellent light transmittance and optical diffusibility.

Other applications: improving the dispersion, liquidity and anti-agglomeration of pigments and ceramic powder.
