Application:
As reinforcing filler for silicone rubber
Silica is one of the most important high-tech ultra-fine inorganic new materials, Because of its small particle size, it has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion, thermal resistance, resistance and other special properties. With its superior stability, reinforcement, thickening and thixotropy, it has unique characteristics in many disciplines and fields and plays an irreplaceable role.
