Xiamen Best Fortune is a white carbon black 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 silica 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. The fumed white carbon black is used in rubber, tires industries.
