Application:
- Precipitated Silica rubber grade ZC Series are mainly used in rubber footwear,Rice roller and Tyre,rubber goods industries.
- ZC Series(Granular and Micro-pearl) are offered low dust,high bulk specific weight that it can be easy to process.
- Precipitated Silica rubber grade ZC series 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
