Abstract :
Influences of alumina trihydrate (ATH) and carbon black content on the tracking resistance of ethylene propylene diene terpolymer (EPDM) compounds were studied. Tracking and erosion resistance of EPDM/ATH compounds significantly improve with the increase of ATH content. Carbon black content up to 1.5 pph has a positive effect on the tracking resistance before and after weathering by a UV-B lamp. It is shown that carbon provides for a more linear voltage distribution, i.e., mitigation of concentration of the electric field due to conductivity of carbon black
