Effect of compatibilizer on the dynamic mechanical and electrical properties of kaolin clay reinforced EPDM rubber

Industrial pollution issue and dark colour of carbon black, clay based non black filler are getting more importance for reinforcing elastomer. EPDM-Kaolin composites with various maleated EPDM concentration have been prepared by mixing on a two roll mill. The rheometry data showed the optimum cure t...
