JK SILICA devoted to the precipitated silica
rubber additive white carbon black powder /precipitated silica
Silica, which is mainly composed of SiO2, features high purity, a high specific surface area that allows it to absorb easily, and high dispersion characteristics. It is mainly produced under alkaline conditions, using a process called precipitation. The properties of silica are affected by the choice of agitation, duration of precipitation, level of the Ph and the temperature and concentration of added reactants.
