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
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.
