Hot sale High Quality Silicon dioxide(SiO2) hydrophobic fumed silica
Product introduce:
1. White Carbon Black (Silicon Dioxide, Hydrated Silica) are a versatile inorganic chemical which are used for reinforcement of rubbers
and plastics, coating and paints, printing inks and cosmetics, antiblocking of plastic foils, free running and free flow of sticky solid and
liquid substances, carrier for pesticides, insecticides, high temperature insulation, stabilizing of beer and silicon rubber.
2. White Carbon Black (Silicon Dioxide, Hydrated Silica) possesses a high reinforcing potential and imparts to rubber compounds
particularly high Shore hardness, tensile strength, tear resistance and abrasion resistance. In order to achieve optimum rubber-technical
data the addition of activators like glycols, amines or other alkaline accelerators is necessary.
