High Quality FUMED SILICA silicon dioxide 150 /200/300


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.
