Silicon Dioxide application

1. Felcosil-140P Silicon Dioxide is a versatile inorganic chemical which are used for reinforcement of rubber seals, battery separators, rubber sacs, belts and tyres industries etc.

2. Felcosil-140P White Carbon black possesses a high reinforcing potential and imparts rubber compounds as the lower specific surface. It can improve high Shore hardness, tensile strength, tear resistance and abrasion resistance, less deformation under compression, and extended products life.

3. In order to achieve optimum rubber-technical data the addition of activators like glycols, amines or other alkaline accelerators is necessary.
