Product Introduction
Introduction
This product is a white, non-toxic, tasteless, odorless, non-polluting non-metallic oxide. Due to its small particle size, large specific surface area, and high surface activity, it exhibits excellent properties such as reinforcement, thickening, thixotropy, insulation, matting, and anti-sagging in materials, so it is widely used in pesticides, Rubber, plastics, coatings, adhesives, seals and other polymer industries.
