Properties: FNG water resistant silicone microporous particles more for white or grey, the product is based on silica gel as raw material after further processing of heterogeneous forming silica gel, it in with homogeneous ordinary silica gel pore structure and adsorption ability also have good resistance to water, which does not burst in the water, thus expanding the application field of silica gel. Purpose: The product is mainly used for air drying in the process of air separation, acetylene adsorption in the process of liquid air and liquid oxygen preparation, compressed air and various industrial gas drying, in the petrochemical industry and other industries as liquid adsorbent or catalyst carrier.
