ZC-165 or ZC-165GR 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 necessaryPackage and storage:1. 20kg/PE bag,15kg/paper bag,800kg/Jumbo Bag 2. Stored in closed and dry premises protected against exposure to volatile substances 3. Storage life: one year in normal storing conditions.
