Xiamen Best Fortune is a precipitated silica supplier with high absorbability, makes it better reinforcement, suitable for filling rubber products, soles, tires, glue, conveyor belts and transmission belts, silicone tubes, etc., providing toughness and high wear resistance.
SD-185P powder grade precipitated silica is 18.5t/40HQ
Precipitated white carbon black is one of the most important high - tech ultra - fine inorganic new materials. Due to its small particle size, it has large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, thermal resistance, resistance and other aspects of special performance. With its superior stability, reinforcement, thickening and thixotropy, it has unique characteristics in many disciplines and fields, and plays an irreplaceable role. Precipitated silica, commonly known as "nano silica", is widely used in various industries as an additive, catalyst carrier, in the petrochemical industry, as a decolorization agent, extinction agent, rubber reinforcement agent, plastic filling agent, ink thickener, metal soft polishing agent, insulation and insulation filling agent, advanced daily cosmetics filling and spraying materials, in medicine, environmental protection, and other fields.
