The influences of nanosilica and modified on cure, compression set, mechanical swelling characteristics are studied in blends ethylene-propylene-diene monomer (EPDM)/styrene-butadiene rubber (SBR). In EPDM/SBR composites, the made from rice husk ash (RHA) was utilised as a reinforcing nanofiller. interaction between matrix at interface is crucial for production composites. This study uses bis[3...
