Application
ZC-185 are mainly used in Shoe making, Rubber Roller and Tyre industries. It is so low dust,high bulk specific weight that it can be easy to process.
ZC-185 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
