Silicon Dioxide (SiO₂)
Felcosil-300 high oil absorption silica has a large surface area and a higher number of active surface functional groups, significantly enhancing the mechanical properties of rubber products, such as tensile strength, tear strength, and wear resistance. Due to its porous structure and large surface area, high oil absorption silica has excellent adsorption properties, making it suitable for adsorbing liquids, oils, or impurities. It is widely used in applications such as pesticides, dry powder fire extinguishers, and catalyst carriers.
