Application:
1. silica is a versatile inorganic chemical which are used for reinforcement of
rubber seals, battery separators, rubber sacs, belts and tyres industries etc.
It is so low dust, high bulk specific weight that it can be easy to process. It’s the same
reinforcement as powder form
2. Silica with granular form 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
1. Package: 20kg/bag or 800kg/jumbo bag
2. Storage: Kept in a low temperature, dry and ventilated place, avoid direct sunlight.
