Özet
This research examined how the addition of mesoporous silicon dioxide (MSiO2) filler affects the rheological, thermal, electrical, and mechanical characteristics of Ethylene-Propylene-Diene-Monomer (EPDM) rubber. In this study, three distinct samples were prepared, each with varying filler loadings: EPDM/5MSiO2 (5 phr), EPDM/11MSiO2 (11 phr), and EPDM/22MSiO2 (22 phr). The mechanical characteristics of these samples were examined, including tensile and tear strength, elongation at break and compression set. Results indicate that minimum torque, the scorch time, cure time, elongation at break %, compression set, abrasion resistance, and UL94-HB-Burning rate were increased while maximum torque, cure extent (CE), cure rate index (CRI), tensile strength, tear strength and current (mA) were decreased with increasing MSiO2 loading. The optimum rubber compound formulation was found in a sample with EPDM/5MSiO2 nanaocomposites which have superior properties, namely tensile strength 13.5 MPa, elongation at break 497 %, 59.4 hardness shore A, tear strength 33.16 (N/mm), compression set 16.4 %, and rebound resilience 64.81 %.
