White carbon black/Precipitated silica/Fumed silica Application：
Precipitated silica, a form of synthetic amorphous silicon dioxide, is derived from quartz sand, a crystalline form of silicon dioxide. The physical properties of precipitated silica can be manipulated during the manufacturing process to deliver products with a wide range of performance-enhancing features engineered for many different end-use applications.
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.
Fumed silica powder (Fumed silica powder)
Productive Process:
Application Features:
1.Thickening and thyrotrophic effect
2.Suspension and emulsification
3.Free-flowing and anti-caking
4.Anti-slipping function
5.Extinction effect
6.Anti-adhesion effect
7.Enhancing reinforcement effect
