Enhanced Mechanical and Structural Properties of NBR/PVC Elastomeric Foam Through Optimization of Nanosilica Filler Content

In this study, we investigated the impact of varying nanosilica concentrations on the cellular structure and rhemetrical characteristics of closed-cell NBR/PVC elastomeric foams. The primary objective was to enhance the structural and mechanical properties of the foam cell structure, leading to improved insulation capabilities through optimization of nanosilica content. Experimental data indicated that the vulcanization and mechanical properties of the elastomeric foams exhibit filler-dependent behavior. The addition of nanosilica resulted in a reduction of both the curing time (t۹۰) and scorch time (ts). Furthermore, SEM micrographs revealed a decrease in foam cell size with increasing nanosilica concentrations.
